A friend said she downloaded an update to Firefox (a version of 6, I believe) but didn't install the update, but the desktop icon was gone. The only way to launch Firefox was from the Programs folder. When clicking on the Firefox file, a "Setup" pop up window appeared stating "Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now?" Clicking "No" does not launch Firefox and clicking "Yes" reboots the computer, but nothing changes after restart and the same series of events keeps re-occurring. When clicking on the safe mode file, Firefox was launched. I went to "Add/Remove Programs" and found Mozilla Firefox 3.6.3. When attempting to remove the program, the same reboot "Setup" pop up appears, and the same non-results as previously described, persisted. I deleted all Firefox files and deleted the update set up .exe files. I again tried to remove the Firefox 3.6.3 program, with the same outcome as the previous attempt(s). I went to the Firefox website and downloaded the updated Firefox 7.0.1 set up .exe file, saved and ran it. When I reached the Setup Wizard page that prompts a "Standard" or "Custom" installation, I clicked on Standard and the same reboot pop up window appeared, again with no change after the reboot. So I have a Program installed (Firefox 3.6.3) with no files, and which can not be removed, an executed update/download .exe for Firefox 7.0.1 that can not be completely installed due to the failure to update by reboot problem. I'm out of ideas on how to try to resolve these problems. Any help would be greatly appreciated! Thank you
