Tried to uninstall Mozilla Developer Preview 3.7 with "Add/Remove Programs", Revo Uninstaller and "C: Programs Files/Mozilla Developer Preview/Uninstall/helper.exe". Nothing works. How do I remove ir?
1) Log in as Administrator
2) Follow those instructions from https://www.mozilla.org/projects/devpreview/releasenotes/ :
Uninstalling the Mozilla Developer Preview
From the Start menu, choose Control Panel. When the Control Panel appears, double click Add/Remove Programs. Find "Mozilla Developer Preview (3.7a5)" in the list and click Remove to uninstall.
Does that work for you?
Unfortunately, no. Neither does Revo Uninstaller nor "C: Programs Files/Mozilla Developer Preview/Uninstall/helper.exe".
