I'm getting the blank screen when running a report on my test server running windows 2008 64bit on IIS 7.
The reports work fine on my development box running vs2010 on a windows 7 machine.
I also get a different error on other reports on my test server that says "logon failed unable to connect: incorrect log on parameters." These reports also work on my development machine.
I have also tested them on a windows 2003 server running IIS 6 with the same problem.
All these reports previously all worked with Crystal Reports for Visual Studio 2008.
I have installed the CR 2010 run-time files on the test machines.
To load the reports I use one form and pass in the report name via a query string and then loop through all the tables to load the connection information...this has worked well for me until upgrading them to CRVS2010.
Any help will be much appreciated. .
