What to install in Crystal Reports 8 and SQL Server 2000

A few years ago, I developed some apps in VB6. The dbms was SQL Server 2000 and the reporting was built with CR8. An old client now needs a few fixes, so I installed VB6 on my Vista machine and loaded the said project

The project needs CR8 and SQL Server 2000 to compile the exe. If I do not want to do install them in full, what specific files of each do I have to make available to the project to ensure it compiles properly?

Any help will be greatly appreciated.
