A solution to reinstallation (?) Rated 1 out of 5 stars
I hate this addon and have also been plagued by it being reinstalled by MS.
I *think* I found the solution though....
1) Start with this: http://support.microsoft.com/kb/963707
2) Use Method 2... BUT ... only do steps 1 and 2.
Yes, the Preference isn't there, but you can create a new one (right click anywhere in the preferences wiindow... and... New) and then Reset it as instructed.
The addon is gone from my addons list... and... I think MS will still see it's installed because I haven't messed with their folder.
I'll repost if it comes back.
