Crystal Reports KeycodeV2.dll not found on Windows 7

I have an application developed on Visual Basic (VS 2003) and using crystal reports (the integrated to VS). All features of my application works fine on Windows 7 (64bit) but Crytal Reports.

There are some cases discussed about the Crystal Reports not supported by Windows 7.  But I am still confused because the error message seems not related to a compatility problem. I received this error before when I was working on obfucation and key related issues of CR.

Is there any quick solution that may fix the problem?

I receive following error on Windows 7 when I try to preview my report (this does not happen when installed on Windows XP).
