I have uninstalled and rebooted several times. No dice. Keep getting error and Firefox won’t install.

Also turned off computer for a while

Feels like registry problem

Let’s do a full clean re-install;

Note: Firefox comes in three or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.
