The format of the dll is invalid

[Dinos]

I recently upgraded from Visual Studio 2003 to Visual Studio 2005 and i'm
having trouble running my InfoPath forms. My solution compiles with no errors
or warnings but when i open my form i get the following error

InfoPath cannot open the selected form because of an error in the form's code.
The format of the file 'EngineeringChange.dll' is invalid.

I have seen 2-3 posts out there but i cant seem to find a solution to this
problem.

Any help will be very appreciated.

Thank

Did you create an "InfoPath.exe.config" file? If so, rename it to "InfoPath.exe.!config" and try again.

Greg,
There was an "InfoPath.exe.config" file at the same location as the
InfoPath.exe file. Once i renamed it everything worked just fine. I did not
create the config file so i'm guessing VS 2003 or VS 2005 created it.

Thanks for your help.

Glad to help. Just note that if you ever have to go back to VS2003 for your work, you might need to rename the file back to InfoPath.exe.config.
