Firefox can’t install on Clients on Domain Server with GPO Policy

ISSUE:

Some customers are on a domain server that have a GPO policy that prevents the installation of Firefox. When they try to install the program, they get an error saying policy forbids it.

SOLUTION:

The workaround is to:

1.  Clear the user’s temp folder (ex: C:usersGregappdatatemp)
   
2.  Run the Firefox installer.
3.  An error prompt will appear saying policy prohibits the installation. Keep the prompt open.
4.  The installer data should folder pop up in the users<user>appdatatemp folder.
5.  Now copy the installer data from temp folder to c:dansupport (or any other folder)
6.  Close the error prompt from  before, then run the installer EXE in the C:dansupport folder
