After converting VS05 solution to VS08, "Error 83 Could not load file or assembly 'CrystalDecisions.CrystalReports.Engine, Version=10.2.3600.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The system cannot find the file specified. C:\Users\...\Documents\Visual Studio 2008\DotNetApps\DGS VS08\web.config 107 "

The VS05 version of crystal reports is not the same as the VS08. The copied web.config file may be pointing to the previous CR version and will cause an error. Replace with the following:

--add assembly="CrystalDecisions.CrystalReports.Engine, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"
--add assembly="CrystalDecisions.Enterprise.Framework, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"
