A common problem I see in various developer forums is trying to build an installation package with the Crystal Reports merge modules or running an application with Crystal Reports on another machine is that the registration code is often forgotten. You may see an error like the following on another machine where Crystal Reports has not been registered:

To make sure this doesn't happen, be sure to register Crystal Reports for Visual Studio .NET when opening a report file, for example, and enter the registration code you'll get back from Crystal Decisions' registration page into regwiz.msm (2002) or Crystal_regwiz2003.msm (2003) in the "License Key" custom property, as you see below:
