I was trying to update a old laptop when I hit into this crazy dialog from Adobe Acrobat 9.1 on my Windows Vista.
Adobe 9.1 bug on Vista
Apparently Adobe expects the user to know how to kill a “Windows Explorer” process and also the “Ignore” button is disabled. Kill Windows Explorer process ? You miss be nuts !
What was Adobe thinking when they did that ? I have no choice but to revert to Adobe Acrobat 8.1.3 to get things working. 
Which is by the way HALF the size of Acrobat 9.1 !
I may have to get rid of Acrobat if it still continues to bug me to heavens. FoxIT here I come !
