Firefox.exe is missing from C:\Program Files\Mozilla Firefox after installing V. 8.0 or V. 8.1

Question

After updating to V. 8.0 from the previous version, the install went OK until it tried to launch Firefox. It then said the path for the shortcut was invalid. Upon checking Firefox.exe was missing. The uninstaller program is also missing. I uninstalled using Revo Uninstaller and tried again - same results. V. 8.1 is the same.

Answer 1

I suspect you may need to modify your Windows registry settings to make the changes permanent. That said, I believe the command line options you wish to remove act as safeguards, I would caution against removing them.
'''-requestPending'''<br>
Tells the application that there will be a Windows DDE request to open the same url specified on the command line.
(Windows DDE is a method for transferring data between applications.)
'''-osint'''<br>
Tells the application that it is being launched by the OS shell.
'''-url URL'''<br>
Open URL in a new tab or window, depend on the browser option.
For more info, see [https://developer.mozilla.org/en/Command_Line_Options here].
You could try removing the -requestPending option (leaving the other options) and uncheck/clear the "Use DDE" checkbox. This may speed things up.
With regards to editing the Windows registry, please see [http://support.microsoft.com/kb/310516 here]. '''Remember to back up your registry first!'''
I believe you will need to modify the following registry keys:
Software\Classes\http\shell\open\command<br>
Software\Classes\https\shell\open\command<br>
Software\Classes\ftp\shell\open\command<br>
