Thank you, Ludek. Since this is our only CR product, I suspected there would not be any 10.2 assemblies anywhere. In the process of reinstalling I followed the developer guide and checked the version of CrystalDecisions.CrystalReports.Engine and found 13.0.2000.0 and 9.1.5000.0. Since I did my VS2010 install as an upgrade from VS2005 as an upgrade from VS2003, perhaps 9.1.5000.0 came from that VS2005 installation and wasn't removed when I uninstalled VS2005 and VS2003. But, evidently, that version of the assemblies is not an issue...unless you tell me otherwise.
Thank you for your input.
