Would be nice to provide the solution or procedure to all users with this problem!
In my case - Pchooklaunch64.exe crashed even if Tuneup-utilities have been installed after proper installation of Total Security 2011.
So what is the solution? Not using TuneUp-Utilities?
Thanks for publishing more detailed informations on how to deal with that issue
