I don't see why not. At the very most, you'd have to set compatibility on the executables associated with the compiler, but I doubt you'd even have to do that.I didn't even know Borland was still making compilers...

Keep in mind that you cannot mix 32- adn 64-bit code in the same process. This means that if you're using external controls and libraries that are 32-bit only, your application must also be 32-bit only.

Are you sure the application you installed was not compiled as a 64-bit application. A 64-bit application installed in the "Program Files (x86)" will not run as a 32-bit one. Also, you set your 32-bit DSN via %windir%\SysWoW64\odbcad32.exe.
