Thanks tamhas,
I have decicded to install a copy of Progress 9.1c on a "sandbox" server - Windows Server 2003 R2 - so I can at least open these Report Builder reports to see what they are doing. After installing it and the patches I have, the Progress Exprorer reports the following:
MMC could not create the snap-in.
The patch file I have is call 91C27. Will 9.1C run on WS2K3? Do I need another patch?
Thanks...
