I have a devlopment environment set up on my PC. I have saved off the client for NAV 2009 SP1 both the classic and RTC before uninstalling so that I could install NAV 2009 R2. After installing the NAV 2009 R2, I am no longer able to do any layout designing for NAV 2009 and NAV 2009 SP1. It gives me the message: It is not possible to instantiate the Visual Studio bridge. I have tried taking a report from SP1 to a R2 test database and then taking it back to the SP1 database. It seems to work fine but when I try to run the report in the RTC client It says the report is in a failed state. Compiling the report gives the message about the bridge.
Is there a work around for this or do I need to set up a second development environment just to do reporting in the NAV 2009 and NAV 2009 SP1 versions?
