Hi,
we have a VS solution containing one SQL Server report project only,
created with VS 2003 that was free of problems so far. We have
uninstalled VS 2003 and installed VS 2005. VS 2005 converts/updates
this solution without errors.
When opening the solution in VS 2005 an error message says:
"The application for project ....rptproj is not installed.
Make sure the application for the project (.rptproj) is installed."
What application is meant here Where do we install it from
Thanks for your help!

Report solution does not open anymore after conversion to Visual Studio 2005

I assume that you are working with a RS 2000 report server. RS 2000 report projects can only be edited with VS 2003. You can install both VS 2003 and VS 2005 side-by-side on the same machine.
If you have upgraded to RS 2005, you need to install the Business Intelligence Development Studio witch comes with SQL 2005. It is an add on that works with VS 2005 and can edit RS 2005 report projects.
