On our TS’s I used to have Visio Viewer 2003 and full Visio 2003. I needed to have both as only a handfull of users have permission to use the full Visio program but everyone needed to view Visio files.
I had it configured so that if anyone double clicked a Visio file it would open via Visio Viewer (IE).
I have just upgraded to Visio 2007 and installed the relevant Viewer but can not find a way to force the viewer to open visio files and not use the full program.
I tried the command line that worked with the 2003 versions but that no longer works.
