Something you need to be aware of, Crystal 8.5 is the LAST version where reports could be compiled. So, if your version of Crystal is ever upgraded, any work you do here would have to be thrown out and rewritten.
I would recommend building a VB.Net application using the CrystalReportViewer component that will actually display the report without having to run an exe.
If you have to keep the .exe format, there are ways to do that too.
