Is it web-based? If so, installing your app with the 32-bit binaries is fine. Just enable 32-bit applications in the Advanced Settings of the application pool.
Hi Case,
thanks for your help! Unforunately it's not web based. It's running as a windows service and this service doesn't start at the 64 bit server. I don't know how what to change to make this possible.
Thank You!

Any clues in the server Event Viewer in the form of error messages?
regardless, you should be able to install a 32-bit service. You may or may not need something like the Corflags.exe utility that installs with Visual Studio. It's worth a try.

Use the /32BIT+ flag and see if that helps.
