I click RUN to start Firefox install on my desktop PC. My "install new software" permissions dialog box appears. I give permission as administrator to run Firefox Install. Firefox install wizard window never appears--everything just stalls. I had no trouble installing Firefox 9 on my laptop.

Try to disable your anti-virus software temporarily to see if that makes installing work.

Disabling Anti-virus did not work. It must have something to do with my administrative permissions in Windows Vista. Other updates have worked recently, but not installing Firefox.
