OS: Windows 7 Pro x64 SP1
Acrobat Pro v11.0.1
I have set location of my Temp folder to another drive F:.
This folder is pointed by both %TEMP% and %TMP% environment variables.
My user (ex. "SomeDomain\SomeUser") belongs to Adminstrators group and set as owner of this folder.
Acrobat is run under regular privileges of my account (UAC is default).
At random time intervals Acrobat would change the NTFS file permissions of the Temp folder and remove my user (i.e. "SomeDomain\SomeUser") from the permissions list.
Here is an audit event log entry (EventID 4670):

New Security Descriptor: D:PARAI(A;;FA;;;BA)(A;OICIIO;GA;;;BA)(A;;0x1201df;;;WD)(A;OICIIO;DTGWGR;;;WD)
This causes various runtime errors when installing application.
