Answer 1

I had a similar issue but with a console application in Visual Studio 2008. The project's Platform Target was set to "Any CPU" which defaulted to 64 bit, and when I tried to access data using a 32bit ODBC driver I got the error described by @afsane. My solution was to set the Platform Target to x86:

Answer 2

I was also having this problem but the reconfiguring of the access driver to 32 bit did not solve it.

I was running a .vbs script from the task scheduler. It gave me the 800004005 Error architecture mismatch error.

I was running the 64 bit Windows Scripting host instead of the 32 bit version. As soon a I specifed the 32 bit WSH the code worked like it did on my Win 2000 server. No errors

If you use the 64-bit odbcad32.exe to configure or remove a DSN that connects to a 32-bit driver, for example, Driver do Microsoft Access (*.mdb), you will receive the following error message:

The specified DSN contains an architecture mismatch between the Driver and Application

To resolve this error, use the 32-bit odbcad32.exe to configure or remove the DSN.
