Acrobat Reader Pro stop working every few weeks

Our employes have all the same error.

After a fresh install of CS6 with Acrobat Pro, Acrobat Pro stopps working after a few weeks.

If the Problems is active, it isn't possible to start Acrobat Pro, the mouse cursor starts for a second the running wait circle, that's all. In Taks Manager i can see acrobat is started but after 1 seconds the process stopped and disapears from taks manager.

It's always the same problem, a reinstall of Acrobat Pro from the Setup of CS6 fixes the problem.

I installed all updates, i created new windows profiles etc... always the same error.

Do you have a hint how to fix this ?
