Same problem running CS6 Master Collection Acrobat X Pro on Win 7 64-bit. Had just created a .pdf from a webpage by printing to Adobe PDF. Gave the file a name, saved it, it popped up on the screen just fine and then Acrobat promptly disappeared. Now Acrobat will not launch. Have tried the usual gambit of solutions to no avail. Seems obvious to me something in the last update FUBAR'd Acrobat. Sorry for the blow by blow that is about to occur below, but I am trying to give as much info as possible so that maybe Adobe will get this fixed ASAP. I just deleted the C:\Program Files (x86)\Common Files\Adobe\Adobe PCD\cache\cache.db file. That does allow acrobat to launch, but it launches to the EULA agreement (see screenshot). I click "accept" and it there is no animation on the button. It acts like it is not accept the selection, but if you wait a couple seconds you get this screen: Apparently I have a trial good for 89+ years :^)... anyway, click to License This Software and get this screen: I select Sign In and it takes it a bit, but eventually gets to provide serial number screen: Of course, guess where my license number is? Yep, saved as a .pdf.... so I exited out of the license page (NOT backed out) and restarted it with the intent of using it in trial mode to get the license number I need. When it launched, it went to the splash screen and seemed okay, so I open a file and it seems fine. I then click help>product registration. It brings me to the CS6 Master Collection screen and asked for me to enter my adobe id/pw. Upon doing that, I receive this And it appeared to be working now. Acrobat is showing me it is at version 10.3.1 But it is buggy. I can work in a file for a few minutes then the Master Collection Trial page already shown above pops up, my license status that was okay a few minutes ago is now back to "Complete/Update Adobe ID profile and we are in a loop of following the above steps over and over. *sigh* I've got things to get done today! I'm going to use it for a while and see what happens. . I'll post an update later. If anyone has any ideas or further info please let me know. Thanks!
