Trying to install newly downloaded firefox (had previously removed about a month ago through programs uninstall), however when I try to run the install, it says a previous version is detected, and the system must reboot. System reboots, but install never happens, I go to run the download again, and it appears I'm stuck in an infinite loop. I can't get latest version firefox to install

I succeeded in installing Firefox after getting this message.

I went to add/remove programs to verify that Firefox wasn't on the list, then I went to the program files directory and deleted the Mozilla/Firefox directory that was left over from the uninstall.

I attempted to reinstall Firefox and, voila, it installed with no issues.

I know it can be dangerous to delete a program directory, but if you have properly uninstalled the program itself and it isn't in the add/remove list (but still exists in the program directory), deleting the parent directory for the program should affect system performance.

I have done this dozens of times over the years and never had a problem (I have NEVER deleted a system directory though. That would be a BAD idea).

I hope this helps.
