An ADO-based application that is compiled in Windows 7 SP1 or in Windows Server 2008 R2 SP1 does not run in earlier versions of Windows

Question

I have read many articles about this problem, but I can't really see where the solution is for me.
I need to compile a Visual C++ program that uses msado15.dll. I have Windows 7 SP1 with Visual Studio 2010. I'm targeting Windows Server 2003, 2008 and 2011.
In the update text in this article: http://blogs.msdn.com/b/psssql/archive/2011/10/03/yes-we-made-a-mistake-and-are-finally-going-to-fix-it.aspx, it says that the fix is published as the article http://support.microsoft.com/kb/2640696. But at other places I
have read that you should not do this update and use the updated msado60.tlb file instead. Where can I find that file, or does it update from "Windows Update"?
I found a "fixed" file called msado60_backcompat.tlb on a blog, after using it it works on WinServer 2003 and 2008 but not on Windows Server 2011.
Any ideas how I should proceed to solve my problem?

Hi flindbys,
Thank you for posting in the MSDN forum.
Based on your description, I’m afraid that it is not the correct forum for this issue, since this forum is to discuss the VS IDE.
If this issue is related to that blog provided by you, my suggestion is that you could add a comment
here, I think you could get dedicated response there.
In addition, I also found some information like the following contents:

Whether this issue is related to the SQL Server Data Access? If it is related to it, maybe you could post this issue to this forum:

Anyway, since it is not the VS IDE issue, I am moving your question to the moderator forum ("Where is the forum for..?"). The owner of the forum will direct you to a right forum. Thanks for your understanding.
