running program across PCs

[koumodaki]

I have written a program that enumetares a USB devices connected to a PC and obtains all the interface strings. I am using SetupDI APIs I compile the program on PC1 and everything works fine. When I copy the executable of my program [along with all files in release dir] to a different PC, say PC2 and execute it, the program does not return any USB interface strings. But when I compile my program on the PC2 and run it, I get all the USB interface strings Why does this happen? The configurations of both the PCs are same.

How so, Mike? It sounds as though the second machine indeed has Visual Studio on it.

Just a wild guess, I really had no concrete ideas from reading his post. Should I not have done that?

More often than not, the answer to "Why won't my VC++ application run on a machine other than the one it was compiled on?" is either the reason you stated, or the application was mistakingly compiled in debug mode. However, he indicated that both machines had VS installed. I'm still baffled.

Not all installations of VS are equal, for example a Platform SDK difference. No reason to be baffled given the lack of information we have, this thread calls for a :beer: :)

But didn't the code compile fine on both machines? If the code was using something specific to the SDK or the DDK, and one of the machines did not have that, I would expect a compile error, not a run-time error.

Agreed.
