Hey there, I'm running into problems trying to install a add-on under Firefox 24 when running under Windows 2000 with UURollup v11 2013-09-02d installed. For example, when I try to update the latest version of GreasyMonkey (v1.12), I'm getting a error message that "There was an error installing GreaseMonkey". When I try again, the error message repeats. Also, when I try to download a add-on from Mozila's Add-ons extensions website, I get a error that "(add-on) cannot be installed because Firefox cannot modify the needed file". And when I updated my machine to UURollup v11 2013-09-02d, the installation did not complete successfully with the Event 4373 error message in the EventLog: "Windows 2000 UURollup-v11-d20130902 installation failed. Access is denied." And here's the full log for complete details: As far as I know when I tried to reboot my machine, I ran into a BSOD that the login process failed. I don't clearly remember which STOP error it was though, but I managed to go into the Recovery console to revert the botched update that caused Windows 2000 to not operate correctly, if not at all. And since I removed the uninstallation for UURollup v11 2013-09-02d, I can't uninstall it now. Is there a way to fix this mess that I gotten into and is there a good update to UURollup v11?
