I upgraded to V.30 from V.29. Now Firefox is NOT working, WHY?
On my desktop (Gateway All In One/Windows 7), I was attempting to upgrade Firefox V.29 to V.30. After restarting I received this message......"The version of this file is not compatible with the version of windows you're running. Check your computers system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher". I am running Windows 7, 64 Bit. I am sending this message from my Laptop (because the browser on the desktop WILL NOT come up) running Windows 7, 64 Bit and Firefox V.29. It has already tried to upgrade to V.30. I did not upgrade to V.30.

Do a clean reinstall and delete the Firefox program before (re)installing a fresh copy of the current Firefox release.
- Download the full Firefox installer and save the file to the desktop

If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
- Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program before installing that newly downloaded copy of the Firefox installer.
- (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
- (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
- It is important to delete the Firefox program to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
