This is closely related with my question in theother post.
The application I received from someone was written in Visual Basic. Okay, that's fine, I thought. Let's take a look. Subsequently I got to know that Visual Basic 2005 could be downloaded for free. So I did. However, it turned out to be that I can't get this application get to work anymore after I installed Visual Basic 2005. Even deinstalling VB2005 didn't help.
Reinstalling the application I mentioned lead to some comments about older files that were in its distribution: expsrv.dll, vbajet32.dll, itircl.dll, itss.dll, hhctrl.ocx. Apparently the files belonged to the 2.5 version of MDAC. The MDAC on my computer is version 2.7 (came that with Visual Basic 2005?). Before ending the installation there is an error message "while registering c:\...\msado25.tlb". I don't know if that's a problem.
When starting that application I get the message: [Microsoft] [ODBC Microsoft Access Driver] '(unknown)' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.
Can anybody help me? Thanks a lot!
