We have upgrade to acrobat 11.22 however on some machines is wont open, i see it is thinking. platform is windows 7. When i uninstalled and installed version 10.xx it works fine.

On the new version 11 i see it is trying to launch Acrobat however i assume that some process are blocking it. I see adobe manager process starting intermittenly in the task manager.

Any help ?
