I'm using Firefox 17.0 and i tryed to install the latest. But i can't even install it because before it starts it says "Please Reboot to install OLDER version!" Help me! I also can't use the Firefox installed!
Solved! Go to Solution.
Um... I can't uninstall the current Firefox. It shows the same error it does trying to install newer/run FF! I've uploaded a picture of the error.
There may be some changes that haven't been handled yet. Try to reboot the computer one or more times to see if that makes this alert disappear.
You see... I restarted my computer 20 times! And it's still there!
I once had problems with a Windows update. While the install program
downloaded, it could not replace the old program with the new. After a
LOT of on line and help searching, I discovered that the uninstall file for
the old program was missing. Going back to Microsoft help, I found the
FIX-IT programs. Once I told FIX-IT what program was giving me problems,
that was it. After, I finished the updates. Go to this web page and check
Fix problems that programs cannot be installed or uninstalled
Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps to remove the program.
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
If you keep having problems then also create a new profile.
