Strange case with crystal report

I am using crystal reports CR XI R1 and CR XI R2 in the application. When I run the application in Windows 7开发者_开发技巧 64-bit OS as 32-bit application, crystal reports works perfectly. However, if the same application is installed in Windows 7 32-bit OS, crystal report doesn't work.

Shouldn't it be opposite of the above case? I thought it should run in 32 bit OS and will fail in 64 bit. Is it a crystal reports issue, or am I doing something wrong?

All suggestions are welcome.

How does it fail?

Here are a few rules to follow deploying .NET application that uses Crystal Reports:

• You need to install the Crystal Reports Basic Runtime for your OS (32bit or 64bit) NOTE: This needs to be done on the host as well after you deploy it. This registers the runtime in the GAC.
• When you import assemblies into your project, make sure that you import them from the
  GAC (C:\Windows\assembly\GAC_MSIL...) and always use the version 10 assemblies because the setup project doesn't seem to work with any other
• Crystal only works with 32bit (emulated or normal)

This might not fix your issues but it is good to get these out of the way...
