Crystal report error - System.AccessViolationException: Attempted to read or write protected memory.

Question

I keep getting this Crystal report error while trying to view the report from an application hosted in IIS.

The code -

    ceEnterpriseService = ceSession.GetService("", "InfoStore")
    ReportApplicationFactory = ceSession.GetService("RASReportFactory").Interface
    ceInfoStore = New InfoStore(ceEnterpriseService)

The web server throws an unhandled win exception as soon as it passes "New InfoStore(ceEnterpriseService)" line.

I have Crystal enterprise 10 installed and am using VS 2012/.NET 4.5. I have to use Crystal enterprise 10 since that is being used by the client. I also had a different version installed and un installed some time back which broke some of the reports while I checked in. Resolved that by asking the clients to load their set of dlls.

Could this error also be an outcome of incorrect versions? How do I check what version is required. I'm kind of lost in this. Any help would be appreciated.

Thanks.

Ok. This is fixed, in case someone faces this issue.

There was some issue with the crystal report designer on my development machine. Fixed that and the reports worked fine.
