C:\Windows\Downloaded Program Files. The only one I show on both an XP and 2003 box are a "consoleutilties class" with a version of 6,0,0,2010. The server also has an appweaver control, but I believe that is specific to the server.
One question would be what version of .net do you have on the system? Not sure if it's a requirement or not, it shouldn't be for just a console, but I'm just musing.
