Acrobat XI Pro automatically closes itself with no messages etc. after few seconds

Question

Greetings all,
I don't know why but my Acrobat XI Pro (11.0.0) automatically closes itself (with no warning, no messages etc.) after few seconds. I installed the AXI as a part of the CS6 Master Collection on my Windows 8 (x64) laptop. Just as suggested at some other posts in the forum:
I checked the "security settings (enhanced)" tab but the protected view option is already off.
I searched for the eula.exe under the "Program Files (x86)\Adobe\Acrobat 11.0" folder but there is no eula.exe. May it be not present because I installed it as a part of CS6 Master Coll. package?
I am using Eset Endpoint Antivirus as a third party Anti Virus Software.
The problem occurs when:
I open up a pdf file from outlook etc.
I manually open a pdf file from windows explorer
I open adobe acrobat with no file to view
As I mentioned above, I see no error messages or warnings during the closing down. It acts as if I clicked the close button on the top right corner. I know that there are a lot of posts in the forum about this issue, but none of them helped me to solve my problem. I would be glad if you can help me with this problem.
Thanks,

Hey i was having this issue also with Adobe Acrobat pro... it only seemed to be affecting one program that produced PDF output automatically. When the processes finished the PDF is supposed to be displayed and instead it would rapidly flash across the screen and close. THen i would have to hunt for the PDF to review its content. I tried a couple of things like deleting my preferences for acrobat C:\Users\[your user name]\AppData\Local\Adobe\Acrobat\10.0. You might have to show hidden files. In the explorer window select Organize-> Folder and search options-> once that opens view -> check show hidden files, folders and drives. then navigate that path above. Make sure adobe is closed then delete everything in there or move it off to another folder if your worried it will break it further.
That did not fix the problem though. I opened the application and ran my process again same results (adobe closes pdf auttmagically). so i opened adobe acrobat and navigated to Edit -> Preferences -> look under the General tab and click the select default PDF handler and that seemed to fix my problem. I also disabled the enhanced security look further down in that list under security enhanced. then a reboot so it is possible that the enhance security setting was the cause i think i will play with that for a minute to see if it was but i think my issue was the default handling. good luck
