A few weeks ago, my company blocked Adobe Reader due to an unpatched security issue. However, we recently moved one of our computers to a project that didn't require access to the corporate network, and IT gave us the green light to override Group Policy and re-enable Adobe Reader.
However, this is something we've been unable to achieve. We've tried the following (in no particular order), all to no avail:
Ran the program as administrator
Renamed the program (the blocking is likely signature-based)
Changed the value of "Start" in HKEY_LOCAL_MACHINE\CurrentControlSet\services\gpsvc to "4" (to prevent group policy from applying, even though it's no longer on the corporate domain)
Checked SRP settings under Local Security Policy - nothing was there
Checked AppLocker settings under Local Security Policy - nothing there either
Incidentally, I found a few registry keys with descriptions referring to Adobe Reader being blocked. I deleted all of them, but it didn't help.
Changed the permission settings of the program
Re-installed Adobe Reader
Update: cleared existing Group Policy objects
Is there anything I missed, short of doing a clean install?
Update: I was able to track down the Group Policy update that's supposed to block Adobe Reader (using another computer). But the change in the registry.pol file is "HKLM\Software\Policies\Microsoft\Windows." Doesn't make much sense...
