HOW TO: FIX ERROR - "the 'microsoft.ace.oledb.12.0' provider is not registered on the local machine"

Question

NOTE: i have found hundreds of threads on this error, yet they all seem to suggest using the 'Microsoft access database engine'. however for whatever reason (even though its made for 64-bit office) this did not work on my machine so i was forced to find an alternate method.

this resolution works with:

• 64-bit Windows 7
• 64-bit MS Office
• Please reply to this thread if it worked for you so i can make this a full "compatibility list"

 

trying to connect to an Access database in visual studio but keep getting this error?

try installing this first: http://www.microsoft.com/download/en/details.aspx?id=13255

 

however if, like me, that doesnt work for you, try the following method:

NOTE: this DOES work for office 2010 even though it is for 2007 office, dont ask me why it just does :)

1. download and install this: http://www.microsoft.com/download/en/confirmation.aspx?id=23734

2. in VS click add data source, follow the wizard and enjoy! :)

 

P.S thanks to everyone that helped me at my original thread: http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/ebb05600-055a-44c4-8cd3-d33a79878b23

i did give up and tried storing to text files, but oh my god was that a bad choice! so i came back to trying to resolve this and managed to after HOURS AND HOURS of searching.

this thread is for all of those people being given a hard time connecting to Access databases!

Please share your opinions/ problems below!

Answer 1

The second link worked for me 100%

Win 7 x64 and Office x64.

Thanks a million for this.

Answer 2

It worked for me too!! The second solution. I don't believe it. I tried everything including hard search on registry!

Thanks very much..

 

Answer 3

no problem guys :)

as i say i spent hours trying to find a solution so upon doing so, i felt the need to share it with everyone. i still want to know why it even works!

Answer 4

Second link works just fine.. :)

Thanks.

Answer 5

Well, even installing the non-64-bit (32 bit) version of Access Database Engine 2010 (rather than the 2007 version you suggested) works for me on Windows Server 2008. It is just that the 64-bit version is not working for some mysterious reason!

Answer 6

The second solution worked for me. Thanks a lot. You made my day.

Answer 7

This resolved the problem for me, but caused another one.  I had installed Office 2010 64-bit, then installed the AccessDatabaseEngine.exe from the second link, which resolved my original issue.  Then I tried to install Visio 2010 64-bit and it wouldn't let me, displaying a message saying:

-------------------

You cannot install the 64-bit version of Office 2010 because you have 32-bit Office products installed.  These 32-bit products are not supported with 64-bit installations:

Microsoft Office Access database engine 2007 (English)

If you want to install 64-bit Office 2010, you must uninstall all 32-bit Office products first, and then run setup.exe in the x64 folder.  If you want to install 32-bit Office 2010, close this Setup program, and then either go to the x86 folder at the root of your CD or DVD and run setup.exe, or get the 32-bit Office 2010 from the same place you purchased 64-bit Office 2010.

-------------------

 

I haven't tried it yet, but I assume I could uninstall the database driver and then install Visio and then reinstall the database driver, but this is not something I can put end users of my product through.  I'm wondering if I made a grave mistake in basing my application on an Access database.

Answer 8

it worked for me, but now i get the couldn't find installable ISAM error. 

everything i can find for that error is for Jet. it seems to be a registry error but i don't know how to fix - any suggestions?

Answer 9

I am getting this error when trying to import Excel files to my SQL Server 2008 R2 database. I tried the first method and then the second. The second method took care of the problem. First post I tried, guess I got lucky.

 

Thank you.

Answer 10

Hi there,

Installing the x86 version on the first link did the trick. That's brilliant, thank you.

Answer 11

I have Windows 2008 R2 Standard Server with 64 Bit OS.

 

IT installed MS Office 2010 64 bit version and it did not work.

I installed 1st link and it did not work.

Then I installed 2nd link and it worked. Strange but true.

Thanks a lot.

Jayson.

Answer 12

I installed the two files and the error went away.  Win 7, VS 2010, Office 2010 64.

Answer 25

I received this error when using SQL Server Management Studio and attempting to import data into a SQL Database.  I selected Microsoft Excel as my data source,  the highest Excel Version that I can select is 2007.   When attemting to go to the next page of the wizard I receive the error message in your post.   

I have downloaded and installed the second link to my Windows 7 x64 bit workstation and it solved my problem.   When I go directly to the SQL server 2008 r2 running on a Windows 2008  and bring up SSMS and get the same error again.  So it looks as if you need to install this fix on every maching that you will be running SSMS on,  even if it is the server.  

Answer 26

Thank you very much...

Second link has absolutely worked for me......... 

Thanks again... :)

Step 1 :  Goto Project Menu Project Properties

Step 2 :  Build

              Platform target : x86

              Save

Try this one..

Hope this will works..

Regards Manju K Gowda

Answer 29

If you have installed the AccessDataEngine and are still getting the Not Registered error

AND

you are running IIS7 on a 64 bit server,

MAKE SURE

you have enabled 32-bit applications for the application pool associated with the website.  In IIS,  Right click on the application pool.  In the properties window, the 2nd option from the top is "Enable 32-Bit Applications".  Set it to true.

Answer 30

I installed the 2nd link and tried to run my project and again I found that my project was not working.

But as soon as I used the trick posted by Manju K Gowda ,

My project started working properly.

and for this My connection string was something like this

string filename = "D:\\email.xls";

OleDbConnection strConn = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filename + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\"");

Thanks a lot.

Answer 31

(Second solution) worked for me - Win7 64 / Office 2010 64.  Thanks- you're a life saver!

Answer 32

The second link worked great!

Win 7 X64 and Office 2010

Thank You.

 

Answer 33

I know you said "this resolution works with:

• 64-bit Windows 7
• 64-bit MS Office"

So my question may be outside the scope of this thread, but what does one do if you have a 64-bit PC running 32-bit Windows 7 N and 32-bit MS Office 2010, and trying to connect to an Access MDB file from a Visual Studio (Visual Basic) program using an ADODB.Connection?  Neither of the above solutions works.  I still get
"Error 3706: Provider cannot be found" with Provider=Microsoft.ACE.OLEDB.12.0

Any solution will be greatly appreciated.

Answer 34

I had the problem on SQL mngt Studio / 64 bit Win7 / 64 Bit Office 2010 importing excel sheets

Installing the accessdbengine work for me.

Answer 35

I am developing a Winform application in c# 4, .Net 4.0 runtime. My dev platform is Windows 7 64-bits with Office 2010 32-bits,

I noticed that this error happens when the platform target is set to 'Any CPU'. When the platform target is x86 it works fine.

I havn't checked what happens if the platform target is set to x64.

I suspect that a 64-bits application cannot work with the 32-bits Jet ACE driver.

Answer 42

Hi,

I have installed the program from the second link (http://www.microsoft.com/download/en/confirmation.aspx?id=23734), the first error is gone, but I can't make the connection to Access 2010 files with the extension "accdb".

In the wizard for creating data connection, I have the following error message: Unrecognized database format "File.accdb".

For .mdb files, the connection is ok.

My environment is : Windows Server 2008 R2, VS 2010, MS Office 2010 64 bits

What can I do now ?

Answer 43

Answer 47

Its work for me!!!!!

Windows 7 Ultimate x64, Office 2010 x64

Thanks a lot man!!!!!!!!!

Answer 48

Second link worked totally fine for me (Windows 7 x64 & Office 2010 x64).

btw: I don't think it's strange, that you have to use Office 2007, since you are adressing a driver with version number 12 (Microsoft.ACE.OleDB.12.0) which is the version number of Office 2007. I guess it would work with Office 2010 if you would address Microsoft.ACE.OleDB.14.0.

It worked for me.  In my case I tried to create Excel connection in SSIS using SQL Server Data Tool (SQLServer 2012).  Have to install the access database engine for Office 2007 to make it connect. The error it gave me was "Microsoft.ACE.OLEDB.12.0 is not registered".

Thank you.

Same situation here. I used the second method and it's work!

Thanks for the solutions!

Answer 77

YES!! Brilliant! Worked for me.

Whats bizarre about this solution is on 64-bit Server boxes (2003 and 2008) the "Microsoft Access Database Engine 2010 Redistributable" is all thats needed to fully support older and newer Office files (97-2010). But only on Windows 7 64-bit, even AFTER installing Office 2010 64-bit AND "Microsoft Access Database Engine 2010 Redistributable", it does NOT work! Only after installing the 2007 components does this work. Why?

I suspect this is tied to the fact those old JET drivers are still being registered on Windows 7, for some reason, for backward compatibility. When the older files are loaded, they are addressed with 4-bit pointers, and use the JET, while Office 10 is 8-bit and its components are not removing the JET references. The OLEDB components on Windows 7, even after Office 10 installation, still point back to the 4-bit 2003 Office JET engine drivers, when they should have been upgraded to 8-bit. I guess the 2007 update fixes that.

Answer 78

The second alternative fixed it for me.  Everything was working fine until I upgraded from 32-bit Office 2010 to 64-bit Office 2013; then I started to get the 'provider not registered' errors.  I tried the first option, but that didn't work.  The second option worked like a charm :-).

Thanks for sharing this solution with the rest of us.

Answer 82

The second link works for me as well.  This is "Microsoft Office Professional Plus 2010" 64-bit and Win7 64-bit.

I am still getting the error Microsoft.ACE.OLEDB.12.0 is not registered. I dont understand if I need to do any other steps followed by installation of .exe file? what does the step "in VS click add data source" means?

However, if I use powerpivot i can use the same provider to load the excel files..Can someone help me out what I need to do?



Answer 86

To get rid of this error message on Windows Server 2008 R2 I had to uninstall existing MS Access Database Engine (maybe it was 32-bit) and install 64-bit version of http://www.microsoft.com/en-us/download/details.aspx?id=13255.

I have just resolved this problem on my machine using your method, thank you so much.

My machine is running Windows 7 Ultimate 64 bit + Office 2013 Professional Plus 64 bit

Answer 94

I had previously installed the Microsoft Access Database Engine 2010 Redistributable. I installed your second link (2007 Office System Driver: Data Connectivity Components) in an attempt to resolve the issue. That did not work. I still got the The 'microsoft.ace.oledb.12.0' provider is not registered on the local machine message.

I resolved this error on my Windows 8 64-bit PC by changing the Visual Studio: Build | Platform Target explicitly to X86. I had it set to Any CPU previously.

Answer 95

I can't belive I forgot that solution! This happened me more than once and I still forget to do that simple setting to overcome that unbeliavable error. I was having the error (actually VS just executed and stopped without giving any error) in Release mode, and the code was working in debug mode. These errors always make me think "why am I insisting working as a developer after facing similar pains for 27 years"! :-)

Thank you for reminding this solution. I was about to break my laptop!

Answer 96

I had similar issue with Win2008R2 x64 and custom program which used new Access format (I'm not a developer of it, so I only had an installer).

I had installed this:

http://www.microsoft.com/en-us/download/details.aspx?id=13255

It didn't work, then I had installed this:

http://www.microsoft.com/en-us/download/details.aspx?id=23734

And with two of these (or just the last one) program worked correctly.

Answer 99

I installed Office 2010 64 Bit on a Windows Server 2008 R2 OS.

Getting this error while trying to debug a legacy ASP.NET 2.0 application, I tried downloading the 32 Bit OLE/DB provider. But that doesn't seem to work.

You cannot install both Office versions to the same machine:

Above message box reads (basically):

"You can not install a 32 Bit version of Microsoft Access Database Engine 2010 because a 64 Bit version of Office products is already installed. If you want to install the 32 Bit version of Microsoft Access Database Engine 2010 you must first uninstall the 64 Bit versions of Office products."
