Hi, I tried exporting wineprefix, repeated winetricks dotnet20, and tried again. Still the same error. Either I am simply too novice a linux user to get this going, or something is missing on my system. I have tried to call the program from the command line but can't quite figure out the syntax. I am using the shortcut under my applications menu. Thanks for trying to help - I appreciate it. Sorry I'm slow to pick up on the details. I may simply need to do this at home on my Windows system (the netbook is my "coffee-break" computer and often where I get the most done since my evenings tend to get busy).
