We had a list of Crystal Reports saved in a web app's report folder and use a common page, showreport.aspx, to load each of the report. It was running OK when we used on the old server, O/S Windows XP, SQL 2008 and Visual Studio 2010. Recently after we migrated and upgraded to a virtual server, O/S Windows12R2, with SQL 2012, and Visual Studio 2010, we started to have a problem that shown the message, invalid report file path. Under this new server, the report can be run and shown in the local, but the lost the old and good format. I tested back to the old server (Window XP) with SQL 2012, it is still working perfectly. I wonder there is a compatibility problem because of the change of the web server O/S? Please advise. Thank you!
