Im getting this error

[mikecrf121]

Unable to cast COM object of type 'CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass' to interface type 'CrystalDecisions.ReportAppServer.Controllers.ISCRReportSource'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{31E7715A-8AD0-4D1C-958E-C1BE0A6F2D0C}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

What version of crystal report are you using to run this?? ive tried 64 bit latest CRforVS
32 bit CRforVS
and sp20 32 bit CRforVS

when i try 64 bit
i get a different error saying could not load file or assembly crystaldecsion.reportappserver.comlayer version 13.0 whatever.

any help or fix would be very much appreciated!!!
