C ++ Visual Studio 2008，将项目从64位迁移到32位

Question

I've trying to use my 64-bit C++ application into a 32-bit system, but I've encountered some problems with Visual Studio 2008.

I've just downloaded the solution on my 32-bit pc (Microsoft Windows Xp), and set Visual Studio settings to: Debug|Win32

The compiling phase is alright, but if I try to run the program, the system says:

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: C:\\wspace4\\BioTesi\\BioCpp.dll: %1 is not a valid Win32 application

Somehow the system does not interpret my dll as 32-bit. I think I'm missin' some Visual Studio setting... but which?

How to solve this problem? Thanks!

Have you set up different build paths for the 32 and 64-bit dlls and exes? It's quite likely you have some 64-bit outputs overwriting the 32-bit ones. Some things to try:

• Check out a clean workspace from your version control system so you don't have any unexpected items lying around
• Open the Configuration Manager and check that the 32-bit configuration of the solution is actually building the 32-bit versions of each project
• Use DependencyWalker which will show the .exe and .dll icons with a '64' overlay if they happen to be 64-bit
