When do I need to remove PGP Desktop?

You may need to remove PGP Desktop:

  • On computers where PGP Desktop was previously installed but not connected to a Universal Server. Be sure to decrypt all drives prior to removal and backup any keyrings.
  • On computers where sensitive data has been removed and there is no longer a need for encryption.

Uninstalling in Windows

  1. First, decrypt your drive(s). You can do so by entering PGP Desktop, selecting the drive, and clicking Decrypt
    • Note: Depending on your policy, this may need to be done by the account that installed PGP Desktop
  2. To confirm decryption, PGP Desktop will ask you for your passphrase. Use the passphrase that you use to decrypt the drive on bootup. Decryption may take several hours.
  3. Once the system is finished decrypting, the locked icon in the tray will re-appear, after the spinning black and yellow circle. Reboot the machine.
  4. Once the machine is rebooted, from the Control Panel, select Programs
  5. In the Programs menu, right-click PGP Desktop, then select Uninstall
  6. In the confirmation dialog, click Yes. PGP Desktop will begin to uninstall.
    • If uninstallation does not continue as expected, a dialog box may appear in the background requiring confirmation. If the progress bar hasn't advanced after a minute or so, press the AltandTab keys or minimize other windows and click OK in the PGP Global Directory Unenrollment dialog box.
  7. Once the uninstallation process is finished, PGP Desktop will ask to restart your system. Click Yes. When the system reboots, PGP Desktop will be removed.
  8. However, the uninstall process does not remove PGP account specific data left behind on the desktop. You must delete PGP folders containing account specific information:
    • For Windows XP:
      • Browse to C:\Documents and Settings\%username%\Application Data and delete the “PGP Corporation” file folder.
      • Browse to C:\Documents and Settings\%username%\Local Settings\Application Data and delete the “PGP Corporation” file folder.
    • For Windows Vista
      • C:\Users\%username%\AppData\Roaming
      • C:\Users\%username%\AppData\Local

Uninstalling in Mac OS

Why not use the Uninstall option in Mac OS?

We have found that running the Uninstall option provided by PGP Desktop for the Mac does not remove all components to allow for a clean install. This is a modified version of PGP's directions for manually removing PGP Desktop for Mac OS X. The PGP instructions can be found on PGP's site.
