Question

Firefox 18 does not start after update - missing msdmo.dll

Following the latest update, each time i try to start FF I get 4 consecutive system error windows:

By 3 times the message is "impossible to start the program since msdmo.dll is missing on your computer. Try to reinstall the program to fix the problem". These messages appears in French (I have French language Windows and FF installed). Then the fourth error message is : "couldn't load XPCOM". (this time the message is in English).

msdmo.dll is present in my \windows\system32 folder, while XPCOM.dll is present in the FF folder.

I tried to download and reinstal FF, I even tried the beta version 19. I followed the clean install procedure found on thE Mozilla website with no success. I ran tree malware scanners and found nothing. I'm using MS Security Essentials and the built-in firewall of windows 7.

Internet Explorer is functioning well, as well as a portable version of Google Chrome with has the same addons as my FF setup : Adblock, Lastpass, and Xmarks.

I really don't see what else i can do?
