Create a new custom folder on your server at C:\inetpub\wwwroot\yourEnvironment\Server\reports. You will find a CustomerReports directory already in place, but for reasons I can’t explain, that particular directory doesn’t work. Create a folder, something like CustCrystalRpt and copy all of your crystal reports into this directory.
Next, update all your Report Styles. You may have to fix/tweak the Report Data Definitions.
