installed 6.0.2 on windows 7 version kb2607712 but when firefox starts get error XUL Runner platform version 6.0.1 is not compatible with mivesrion >=6.0.2 maxversion >=6.0.2'. have uninstalled and downloaded and re-installed but same problem occurs.. after this firefox wont start at all.

Chosen solution

Did you make sure that all files in the Firefox program folder (C:\Program Files\Mozilla Firefox\) are removed and that folder as well?

You can try to boot Windows in Safe mode (press F8 on the boot screen) to see if that allows to install Firefox.

You can also try a custom install in a different directory like "C:\Program Files\Mozilla Firefox6\"

tried that twice. if I could get an earlier version I would install and try. First tho I will rollback to a restore point.

Create a New Profile as a test to check if your current profile is causing the problems.

-> Basic Troubleshooting: Make a New Profile

-> If that New Profile works then you can recover your Bookmarks and Passwords from the Old Profile.

-> Recovering important data from an old profile

Check and tell if its working.

This won't help the OP, but FWIW I simply reinstalled 6.0.2 (without doing the uninstall) and all appears to be well.

hhmmm. I created a new directory, and installed ok. checking all the instances of firefox and version references in files across the pc will take a while. but I'll see if I can find the offending snippet.

Installing using the custom option and designating a new directory worked for me also. Thanks for the suggestion.
