Appcrash on SetDataSource of ReportClass

I'm using Visual Studio 10 with Crystal Reports for .Net installed. My development environment is a 64 bit pc with Windows 8 on. Everything works fine on my development pc but when I install the app on the client pc I get an Appcrash windows error on the SetDataSource of the reportclass. The only info on the crash is the KernelBase.dll is the fault module. When I look at Windows Event viewer it says there was a filenotfountexception, but doesnt give the name of the file it is looking for. The client pc is a 32 bit windows 7 pc. I installed the latest 32 bit runtime files on it.

Can you please help me to figure out what the problem is?

Thanks
