Yesterday Firefox worked great. Today I failed to launch. I tried reinstalling it. If installed correctly but fails to launch. I thought I would try a clean install by first deleting all previously installed versions. One very old version "Mozilla Firefox 62.0.3 (x64 en US) fails to uninstall. Any Ideas on How to delete that file?

It is possible that this is only a leftover, orphaned, registry key and that the installation it points to no longer exists. In that case you can cleanup the registry yourself or use a registry cleanup utility.
