I’m of the same mind regarding subscription software. I simply won’t do it. I’ll stick with my Windows 7 and Office 2010. When Microsoft makes those obsolete and tries to get me to upgrade, I simply won’t do it. I don’t trust “the cloud” and I don’t trust any corporation that tries to push me in that direction.
There is a parallel issue involving or likely to affect Acrobat XI Pro the same way. Is there any information about the fix for Acrobat XI Pro, and is the updater block and folder deletion and regedit a general fix for other Adobe products?
