Hello,

This is the error I get on Windows 7.

I tried going to the project screen in vb.net Studio 2008, and changing the
target cpu to x64. This did not work.

Do I have to build the program on Windows 7?


I'm sure this must be a common problem for programs going to Windows 7.

Thanks for any help.

Scott

Hi,

I think you need to set target CPU to x86 explicty and re-compile,
then try to run on Win 7 x64:

or try to use corflags utility:

HTH,

The rule of thumb I always follow is develop, compile and build the
application on the platform it's intended to run on. That means you
develop, compile, and build the application on Win 7 64 machine to be
deployed to a Win 7 64 machines -- Windows XP machine to Windows XP
machines, Vista machine to Vista machines, etc. etc.

Are you sure the Windows 7 version of the PC you are trying to run the
application on is the 64-bit version and not the 32-bit (x86) version?

This is unrealistic.
