Microsoft.ACE.OLEDB.12.0 provider

Question

Hello everyone
I'm currently designing an application in C# and at the same time I'm using databases (with access)
but during compilation, the following message appears: "the Microsoft.ACE.OLEDB.12.0 provider is not registered on the local machine." I did some research but couldn’t find anything, I found a sort of solution saying to switch from 64 to 32 bits (x86) but still no result, I get the following message instead: "the specified case is not valid"
So now I don't know what to do, so if someone can help me that would be super coooooooooooooooooooooool
thanks
ps: I’m working with Visual Studio 2008!!!

Configuration: Windows 7 / Safari 533.1

You need to choose "Target CPU" as X86 instead of "Any CPU" in the advanced compilation options. The driver is not compatible with 64 bits. Once that's done, you won't have this issue anymore.

Good evening,  Can you show us the connection chain?

Hello,  I think there's a problem with the connection string, but I didn't understand ./BDC.accdb  and to check your connection string, see here https://www.connectionstrings.com/access-2007/

Hello,Thank you for the explanation. I suggest placing your database in the bin folder of your application.Then modify the connection string.Application.StartupPath + ""\BDC.accdb"

I'm bringing the subject up again, sorry, but indeed, the solution to the problem is to compile in x86 and not in Any CPU!  Thank you

I THINK THAT THE SOFTWARE DOES NOT SUPPORT ALL THE FILE EXTENSIONS YOU WANT TO IMPORT.

Hello,

I also can't add my database to Visual Basic, this message appears: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

I saw that I needed to change the target platform (target CPU) to x86 but I can't find where to change the platform, I don't have it...

Thanks for your help!!!
