I am unable to open AcrobatPro 9.5.2 on Mac.

Question

This is a new problem for me. I also can't upgrade or even install Acrobat reader. When I click the icon it bumps like it is going to open, but nothing happens. I also see no preferences in my system folder.

There seems to be a LOT of problems with AcrobatPro 9.5.2 on the Mac, but Adobe doesn't seem to be addressing these.  I, like you upgraded to 9.5.2, in my case from 9.5.1 (which worked great), but now there is a host of problems with 9.5.2.  Unlike you, I can open 9.5.2, and I can open a pdf in 9.5.2, I can not save it, and the program hangs --usually within seconds or a minute--when I try to use  any of a large number of the menu items ( I get the spinning color wheel of death foreverrrrrrrrrr....) .
Just as bad, Safari  performance is  also affected.  It is now like a snail, and if I try to download a pdf in Safari using the acrobatPro helper application ( i.e. AdobePDFViewer.plugin) which AcrobatPro installed in my library, I again often-- but not always-- get the spinning color wheel of death--again, and again , and again...  Removing the AdobePDFViewer.plugin from  the Internet Plug-ins  directory of the library directory restores Safari to its previous speedy gonzalas speed, and I can again download pdfs ( using the apple pdf software--not AcrobatPro).  That works for downloads (using the inate apple software), but if you want to use AcrobatPro for anything--crash, crash, crash, Hang, Hang, Hang...
I've made several bug-reports to Adobe, and asked several times for advice on how to get back to version 9.5.1 but its like talking to a brick wall. Not a very nice way to treat your customers.  I am afraid they will not talk to you unless you purchase a new service agreement, even though it is THEIR software update that has made it impossible to use their AcrobatPro.
To anyone else out ther who is contemplating upgrading to version 9.5.2:  DONT DO IT!!!!
