VB6 and Crystal 9.1 to new environment

Medium Priority
Last Modified: 2012-05-06
I used vb6 and crystal 9.1 to develop a project 4 years ago.  I'm trying to reopen the project using Vista, vb6, crystal 9.22.  My disk has been scratched over the years and havnet been able to reinstall 9.1.

Here are my 2 issues that are likely related to not having 9.1 installed?  

Currently when I open a dsr file in development it properly opens the report design and "visual basic 6" immediately has an error and shuts down my project and I have to reopen vb6 and the project.  Ok so I can't open a report without vb6 having a critical error.

I can execute and open the project to generate one of the report outputs but when I try to create multiple reports for some reason I get an error at:
Mainform.CRViewer91.ReportSource = finalDrawNeeds
"Method ReportSource of Object 'ICrystalReportViewer9' Failed"

Are both of these issues just because I don't have 9.1 installed?  Could it be some kind of vb service pack I need to install?  I am unsure where to go I have tried converting the project to vs2008 and my mainform had an error during conversion.  I have also tried using crystal 10 with vb6 with no luck.  Thanks for any advice!

I suspect the issue is Vista

Crystal requires updates to run om Vista.  I don't think CR9 or 10 has been updated through a service pack to run reliably on Vista.

I don't knpw about VB6 it may also require changes.

You might consider upgrading to CR XI.  No further because later versions of Crystal don't support VB6 or com applications.
