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:

1. Ran the program as administrator

2. Renamed the program (the blocking is likely signature-based)

3. Deleted registry.pol

4. 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)

5. Checked SRP settings under Local Security Policy - nothing was there

6. Checked AppLocker settings under Local Security Policy - nothing there either

7. 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.

8. Changed the permission settings of the program

9. Re-installed Adobe Reader

Is there anything I missed, short of doing a clean install?
