I am having a similar problem in a fresh install of windows vista. I used to be able to run the viewer installers, but now I get absolutely no response/feedback/errors/anything when I attempt to run. I have tried running as a user and as admin. Clicking on the .exe file does nothing. Firestorm is acting the same way. However, drivers and other third party software runs without any problems. Why or why has SL started to hate me all of a sudden??????? lol
