Comment (by cypherpunks):

 > I have windows ultimate 7 sp-1 tor has worked fine for months. Today it
 would not start and I have the Couldn't Load XPCOM error.
 > I recently set up a laptop with the exact same operating system and tor
 browser and it runs fine.

 Can you to check if updates installed on the second laptop's windows are
 the same as for the first laptop's windows (include optional KBs etc)?
 Can you try to install AVG to the second laptop too?
