Hi I am getting problems regarding the import of an xlsx table into SQL Server 2014. The Microsoft.ACE.OLEDB.16.0 is apparently not available ie not registered. The PC has the Access runtime 2010 installed but to no avail. Upon installing the Access runtime 2016 it says that I must uninstall Office 2016 altogether (sic!). In the IIS I have checked the Application pool to run 32-bit applications (set to TRUE). Since I have mostly spent my time in an Access developing environment this is quite a new challenge for me.

Shouldn´t it be possible tom import excel tables on the fly? I am aware that SSMS needs ODBC drivers but can´t they be shipped already installed since the products are from the same house. Please advise how to overcome this obstacle without deinstalling Office 2016. Thanks in advance, Tomo.

Hi Tom, You don’t need to install Access runtime 2016 and don’t need to uninstall Office 2016. Based on my test, we can import data from Excel 2016 into SQL Server 2014 by using Microsoft.ACE.OLEDB.12.0, you can use the following steps to import data.

Microsoft.ace.oledb.12.0 Excel

1. You can download Microsoft.ACE.OLEDB.12.0 from and install it on your machine. 2. Make sure SQL Server Service account has read permission on the folder that contains.xlsx file, you can open SQL Server Configuration Manager, find SQL Server Service and open the properties by right clicking it, then you can check the SQL Server Service account. 3. Open SQL Server Management Studio, enable the use of distributed queries by using the following code: USE master GO -CONFIGURING SQL INSTANCE TO ACCEPT ADVANCED OPTIONS EXEC spconfigure 'show advanced options', 1 RECONFIGURE GO -ENABLING USE OF DISTRIBUTED QUERIES EXEC spconfigure 'Ad Hoc Distributed Queries', 1 RECONFIGURE GO 4.

Add the driver to SQL Server by using the following code: USE master GO -ADD DRIVERS IN SQL INSTANCE EXEC master.dbo.spMSsetoledbprop N'Microsoft.ACE.OLEDB.12.0', N'AllowInProcess', 1 GO EXEC master.dbo.spMSsetoledbprop N'Microsoft.ACE.OLEDB.12.0', N'DynamicParameters', 1 GO 5. Insert data to SQL Server table by using the following code: SELECT.

INTO Tablename FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0', 'Excel 12.0; Database=xlsxfilename; HDR=YES; IMEX=1', 'SELECT. FROM Sheetname$') GO Regards, Teige.

In the old times while all the CPUs were 32bit, we were happily using JET OLEDB Provider reaching Excel or MDB files for long time without any issues. After we started using x64 CPUs and x64 Windows machines, we noticed that JET OLEDB Provider is not working. The reason for this was x64 Windows operating systems were not containing x64 bit JET OLEDB Provider but they had 32bit JET OLEDB Provider. We needed to recompile our applications as 32bit by changing the 'Target CPU' as x86 in our Visual Studio Projects (remember that default 'Target CPU' fro a Visual Studio Project is 'Any CPU'), or using a 32bit application pool for a web application just to be able host our app in a 32bit w3wp.exe. Now we have a new guy in the town.

Let me introduce it: 'Microsoft ACE OLEDB Provider'. It's 'ProgID' (in terms of COM/OLEDB) is ' Microsoft.ACE.OLEDB.12'. It does not come within the OS, you should install this manually by downloading it from. The name of the download is ' Microsoft Access Database Engine 2010 Redistributable' as this 64bit ACE OLEDB Provider is the result of our Office 2010. It has been around in the scene with Office 2007 but it was available as 32bit only. I have a web application that use this component to export a large data set to an excel file in xlsx format.

There should be about 12000 rows in the generated file. On a workstation with windows 7 and 'access runtime engine' 2007, with SP2 and another update installed, this works fine. However on the production win2003 server, with the same versions of access runtime engine installed, only about 6000 rows get written to the excel file. There is no error message – the file just isn't complete. We use 'Provider=Microsoft.ACE.OLEDB.12.0'- On a brand new server, with win2008 R2 and access runtime engine 2010 64bit, the same problem occurs, Half the rows are missing. On the old server we set it to use the traditional xls-format instead, and that worked but produces horribly big files. And this fails on the new server.

Maybe we need to install something else to make 'Provider=Microsoft.Jet.OLEDB.4.0' work for producing xls-files. I'm having trouble finding documentation on these components. Any pointers? This is great news! However, when I install on 64bit WinServer2008 and attempt to access an Excel file I get: The 'Provider=Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

The application has properly installed (I can see it in Add/Remove programs). I noticed that the version there is 14.0. Should the OleDb connection look like below? OleDbConnection conn = new OleDbConnection('Provider=Microsoft.ACE.OLEDB.14.0;Data Source=c: temp test.xls;Extended Properties='Excel 12.0;HDR=YES;').

Hi, I have your Case 1 with new Excel 2010 64-bit data I am trying to load into SQL Server 2008 R2 EXPRESS x64. Previously Excel 2007 imported fine, but Office 2010 x64 required uninstall of all 2007 x32 components. I downloaded and installed the AccessDatabaseEngineX64.exe, rebooted and ran the SQL command (resulting in:: 'Configuration option 'show advanced options' changed from 0 to 1. Run the RECONFIGURE statement to install.' ), restarted SQL EXRESS but still get the error: 'The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.'

When I try to import the Excel file. Thanks for any help! Regards, Raj. Hi Oskar, If you check the download page for the ' Overview' paragraph has an explanation answering your situation. Here's the quote from its download page: The 2007 Office System Driver are not intended: As a general replacement for Jet (If you need a general replacement for Jet you should use SQL Server Express Edition). As a replacement for the Jet OLEDB Provider in server-side applications.

As a general word processing, spreadsheet or database management system -To be used as a way to create files. (You can use Microsoft Office or Office automation to create the files that Microsoft Office supports.) To be used within a service program or web application that relies on a Windows service. So, neither ACE OLEDB Provider (either 32bit or this new 64bit) nor our good old friend Jet OLEDB Provider intended to be used in mult-threaded applciations like web applications. Best Regards, Faruk Celik. I am using Visual Studio 2010 Ultimate with SP1 and Microsoft Office 2010 x64 on Windows 7 Ultimate x64 with SP1, when I add an Microsoft Access 2010.accdb file into the VS2010 solution, VS2010 present me a dialog box of 'Choose a Database Model' and ONLY 'DataSet' option is available.

After I click 'Next', I got the error of 'The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. I have already installed'Microsoft Access Database Engine 2010 Redistributable' (AccessDatabaseEnginex64.exe) from and still got this error. What am I missing? @Wyatt, As you already have Office 2010 x64 installed on your machine, you have x64 version of 'Microsoft.ACE.OLEDB.12.0' OLEDB Provider is installed.

Visual Studio 2010 (or 2008, 2005) IDE itself is a 32bit process named 'devenv.exe' (You can check from 'Task Manager', you will '.32' next to devenv.exe like 'devenv.exe.32'). We don't have 64bit version of Visual Studio 2010 (or the old ones), it is/was always 32bit.

As devenv.exe (Visual Studio 2010 for your scenario) is a 32bit process, it cannot reach 64bit 'Microsoft.ACE.OLEDB.12.0' OLEDB Provider or any 64bit OLEDB provider at all. So, you have to have 32bit version of 'Microsoft.ACE.OLEDB.12.0' OLEDB Provider.

Please download AccessDatabaseEnginex86.exe to have 32bit version of 'Microsoft.ACE.OLEDB.12.0' OLEDB Provider on your machine. I'm not sure if it will allow you to have installed on your machine as you have Office 2010 x64.

If it says 'sorry, you have 64bit Office I cannot install 32bit AccessDatabaseEnginex86), you will have to uninstall your Office 2010 x64 and install Office 2010 x86. Hope that helps. Regards, Faruk.

I have downloaded the 32-bit AccessDatabaseEngine.exe and it will NOT allow me to install since it detected that I have installed Office x64. I knew the VS2010 is a 32-bit application. It seems the problem is similar to Outlook x64 cannot ActiveSync with Windows Phone 6.5 because WMDC 64-bit driver is calling the 32-bit version instead of a 'real' 64-bit driver. I think the Office x64 is of no use because of incompatibility with all other 32-bit applications.

As such, I would like to ask what is the 'use' of the AccessDatabaseEnginex64.exe as various guys have mentioned in this comment history? @Francisco As BIDS (Business Intelligence Development Studio) tool itself is a 32bit process (devenv.exe, you can check it from Task Manager), it cannot reach 64bit ACE OLEDB Provider.

You should have 32bit ACE OLEDB Provider installed on your machine. But you cannot install 32bit ACE runtime on a machine with Office 2010 64bit installed. You should uninstall your 64bit Office 2010 and either install 32bit Office 2010 as a whole product or just 32bit ACE Runtime, because you cannot have 64bit and 32bit ACE runtime in the same machine. Quick Question: I have developed a program (VB.NET) on a x86 XP machine that uses OLEDB to read a.XLSX file. The program runs fine on all other x86 machines in the office. However, I would like it to be able to run on the X64 W7 machines we have here too, but am not succeeding.

The x64 machines have x86 Office installed. I tried installing the x86 Access Connectivity Engine (b/c I can't install the x64 version with x86 Office on the computer), but no cigar. My target CPU in Visual Studio on the xp machine while developing is 'Any CPU'. Any idea what I need to do to get this to work for both 32 and 64-bit? Hi Faruk Celik, Thank you for your article.

I had 1 issue re Access 2003 and 64 bit OS. I am trying to insert data from access 2003 to sql server on 64 bit OS. I tried to install Accessdatabaseengine.exe but that didn't work. So I tried for Accessdatabaseenginex64.exe but still I am not getting it. I am getting error like i cant install the driver because of office 2003 products. 1 resolution I got is that i need to uninstall the 2003 office products and install Accessdatabaseenginex64.exe and then again install office 2003. Is that option workable?

Please guide me thru in this. Regards Prashant. Hi Faruk, The exe has been istalled successfully. It is a 64bit OS.

But even after that i get an error saying The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. And the ACEOLEDB.DLL is present in the location: C:Program Files (x86)Common Filesmicrosoft sharedOFFICE14 this DLL which is present in this location is not the newly installed file.

Can u please tell me where the newly installed files are stored and should i execute any commands to use the newly installed files. The system is a 64bit OS and it has MS Office 2007 version installed. Can u pls tell me the steps i need to follow to resolve the error. Thanks, Mahalakshmi.

I am using VS 2010 and created a page that imports data from xlsx file. Connection string 'Provider=Microsoft.ACE.OLEDB.12.0;Data Source=' + strFilePath + '; Extended Properties='Excel 12.0;HDR=No;IMEX=1;TypeGuessRows=0;ImportMixedTypes=Text';' When i run it in VS environment it runs well and the data is imported. But as soon as i try to run it from IIS as virtual Directory i get the problem 'The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.' When i try to build the application with x86 and try to run the application it fails with the error 'Could not load file or assembly 'FinRep' or one of its dependencies.

An attempt was made to load a program with an incorrect format. ' I have checked registry entry and it seems ACE.OLEDB.12.0 is already registered there. Thanks Gunjan. @Nick77, Could you please do 64bit and 32bit UDL Test and let me know in which one(s) you see 'Microsoft Office 12.0 Access Database Engine OLE DB Provider' in 'Provider' list. Here are my blog posts for 'UDL Test' (s). 1) 64bit UDL Test on a 64bit OS TR-loc-Services-farukc 2) 32bit UDL Test on a 64 bit OS TR-loc-Services-farukc This will let us know that which version of ACE OLEDB provider is installed®istered on your machine. If you see that '64bit UDL Test on a 64bit OS' succeeds, high likely your application giving you 'provider is not registered' error message is a 32bit application and you haven't installed the 32bit version of ACE OLEDB.

As the other commenters said you will need to install both of them in passive mode using /passive switch (Check the comments above for details to install both) or if you only need 32bit version of ACE OLEDB, then uninstall 64bit package you installed and install 32bit package (After installing 32bit, be sure that 32bit UDL test succeeds). @Mohamed Zaatar Are you receiving 'Could not find installable ISAM' when running the app inside Visual Studio or outside of Visual Studio? As I'm repeating in my comments above, please do 'UDL Test's on your machine to see if the 'ACE OLEDB Provider' is working fine first. If you get the 'Could not find installable ISAM' through 'UDL Test's too, please uninstall/re-install the 32bit ACEOLEDB provider please let me know: 1) Your Office version 2) You OS version (together with the CPU version: x86? X64?) 3) What is the Excel ifle extension (xlsx? Etc.) 4) What is your application type? (consol app, windows forms app, ASP.NET web app etc; if it is a web app what is your application pool bitness 32bit or 64bit?).

Trying to connect to Excel 2010 file using the above, SQL 2008 64 bit, Office uninstalled, 32 bit driver uninstalled. Installed the new 64 bit driver, rebooted machine and get the following error messages Msg 7399, Level 16, State 1, Line 1 The OLE DB provider 'Microsoft.ACE.OLEDB.12.0' for linked server '(null)' reported an error. The provider did not give any information about the error.

Msg 7303, Level 16, State 1, Line 1 Cannot initialize the data source object of OLE DB provider 'Microsoft.ACE.OLEDB.12.0' for linked server '(null)'. Could anyone help with any ideas. @faruk I don't know if you are still responding to these blog comments. If you are I have a web app with an excel file embedded in the app.

When I run the app on the development machine which has Office 2010 installed it works fine. When I install the app on the Server on which I have run the AccessDatabaseEnginex64.exe, then it will initiate the connect successfully but throw an error on the Query SELECT. FROM SHEET1$ saying it can't find a sheet1$. The only thing I've been able to find is a bunch of people suggesting that maybe the file doesn't have a sheet1$, which is of course ridiculous.

So I am wondering if you had any ideas one why the query doesn't work. I have a web app with an excel file embedded in the app.

The correct solution has been provided by Andreas above. I have 32 bit office on windows 7 64 bit Andreas Marschall 18 Aug 2010 12:15 AM # Hi Faruk, according to your P.S.

2 you say that it is not possible to install 'Microsoft Access Database Engine 2010 Redistributable' 64bit when MS Office 2010 32bit is installed. This is only true if you call AccessDatabaseEngineX64.exe without any arguments. But when you call AccessDatabaseEngineX64.exe /passive then is installs with no complaints in parallel with an existing 32bit counter part. Best Regards, Andreas Marschall. I get the: 'The Microsoft Access database engine cannot open or write to the file '.

It is already opened exclusively by another user, or you need permission to view and write its data' Error. It occurs when running a mailmerge between Excel & Word and sends the word mail files as attachments to email addresses using outlook, all the code is in a VBA script in the source excel file. This worked fine in XP & office 2010 (32 bit), it gets about 25% of the way through the exercise (so sends some fine) but then falls over. Currently running W7E 64bit SP1 & Office 2010. Is this related to the Jet DB issue and will patching my local client with the redistributable file be OK? Sorry I'm just a n Excel user rather than an IT developer so not sure if this make sense.

Hi Faruk, Thanks for your post. I am having a 64 bit dev machine with office 2010 64 bit. I am using this connection string string connectionString = 'Provider=Microsoft.Jet.OLEDB.4.0; Data Source=' + excelFilePath + ';' + @'Extended Properties='Excel 8.0;IMEX=1;'; This works while i am trying to read excel file. Howveer the same fails onto prod machine with the error as System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. — System.Data.OleDb.OleDbException (0x80004005): Unspecified error at System.Data.OleDb.OleDbConnectionInternal.ctor(OleDbConnectionString constr, OleDbConnection connection) Please help. Hello Sandy, It looks like your app is an ASP.NET app because the callstack/stack trace in the error shows calls from System.Web namespace. It is possible that you are getting the 0x80004005 error because your IIS application pool's identity cannot reach to the file you specified in 'excelFilePath'.

Please check this first. Also, JET OLEDB provider will need to create.tmp files under%temp% folder of the user running the process hosting it. In this case, process is w3wp.exe and the user running the process is the application pool identity you set.

Please try 'Response.Write'ing the%TEMP% environmental variable (Refer to: ). In this way you will see the%TEMP% folder for the current user/applicaiton pool identity running your application pool. You should grant read/write access to the%temp% folder.

Our free tool 'Process Monitor' will be your best friend to see the file activities. You should find your w3wp.exe, add a filter to it and see if it gets any 'ACCESS DENIED' for any of its calls.

Hope that helps. I'm trying to Link to an Excel file from my SQL 2012 box running Server 2008 R2. I have installed the AccessDatabaseEnginex64.exe from a server login and I can see the Microsoft.ACE.OLEDB.12 in the list of Linked Server Providers. Faruk, I'm attempting to import/export data back and forth between MS Access 2010 64 bit and SSMS 2012. In the Import/Export Wizard of SSMS, I can not view the Microsoft 12.0 Access Database Engine OLE DB Provider in the Data Source drop down. I have installed the Microsoft Access Database Engine 2010 Redistributable and ran the queries you mentioned above. I received the following message, OLE DB provider 'Microsoft.ACE.OLEDB.12.0' for linked server '(null)' returned message 'Unspecified error'.

Msg 7303, Level 16, State 1, Line 1 Cannot initialize the data source object of OLE DB provider 'Microsoft.ACE.OLEDB.12.0' for linked server '(null)'. I have run the UDL test from the link you provided above, and the test connection failed. Thanks in advance for your time, Tneahr.

Microsoft Error Ace.oledb.12.0

Hi T Neahr, SSMS is a 32bit process and actually you are spawning another 32bit process (C:Program Files (x86)Microsoft SQL Server100DTSBinnDTSWizard.exe) as well when you ran Import/Export Wizard. We have 64bit version of DTSWizard.exe located in C:Program FilesMicrosoft SQL Server100DTSBinnDTSWizard.exe. You can run this directly instead of selecting 'Tasks/Import Data' (or Export Data) database context menu item while you're in SSMS. As you have MS Access 2010 64bit installed on your machine, you already have ACE in 64bit and you should see ACE OLEDB provider in the combobox when you ran 64bit DTSWizard. Thanks, Faruk.
