Software: Disabling features of PGP Desktop

This is a non-supported configuration change..

From PGP Support:

Permanently Disabling functionality in PGP Desktop 9.6.2 and above

PGP Desktop by default installs all the functionality to the software such as Email Encryption. If there is a need to install PGP without certain functionality such as Email Encryption, this article will explain how to do so. Installing without PGP Desktop features will still install all files and drivers for the feature(s) not being used, but are disabled.

Installing PGP Desktop without selected functionality

1. If the installation file extension is already .msi, then go on to step 5. If the file extension is .exe, proceed to step 2.
2. Double-click on the .exe file until the wizard comes up. Do not proceed through the rest of the installation.
3. Click Start, Run and type: %tmp%, this will open up the temp folder. A PGP folder should be listed. Open the PGP folder and inside should be a .msi file which should be copied to the C: drive in preparation for the next steps (You may copy the file to anywhere on the drive, however modify the path according to where you copy).
4. After the file has been copied to the C:\ drive, cancel the installation.
5. Click Start, Run, type: cmd and click OK (For Windows Vista, click the Start button on the bottom left-hand corner of the screen and click in the “start search” field, then type cmd and hit enter).
6. From the command line, type: cd\ and hit enter. This should return the C:\> prompt.
7. Type: msiexec /i [Name of installation file just copied to the C: drive] PGP_INSTALL_MAPI=0 and hit enter. **Change the install option for the feature you would like to disable as listed below. If the name of the installation file is called PGPDesktop.msi and installing without Email Encryption for Exchange, the command would look like this:

C:\> msiexec /i PGPDesktop.msi PGP_INSTALL_MAPI=0

8. The installation should now proceed. Follow the on-screen instructions and reboot when completed.
9. Now the PGP feature for Email Encryption for Exchange has been turned off permanently

**Installing without multiple features is also possible. In this case, list each feature in the msi string as needed. Below is an example of installing without Email Encryption for Exchange and Whole Disk:

C:\> msiexec /i PGPDesktop.msi PGP_INSTALL_MAPI=0 PGP_INSTALL_WDE

If the feature disabled during installation is needed in the future, a reinstall will be necessary and the msi string above will need to be ran again, this time changing the “0” to a “1”. The example below is reinstalling with the Email Encryption for Exchange enabled:

C:\> msiexec /i PGPDesktop.msi PGP_INSTALL_MAPI=1

PGP Install Options:

Below is a list of all the msi options available. With PGP Desktop 9.6, the features are disabled, but are still displayed in the PGP Desktop User Interface. With PGP Desktop 9.7, these features are disabled and removed from the User Interface altogether.

The only options that work with 9.6.2 and 9.6.3 are

PGP_INSTALL_GROUPWISE Email encryption for GroupWise plug-in
PGP_INSTALL_LSP Email encryption for POP/IMAP traffic
PGP_INSTALL_MAPI Email encryption for Exchange
PGP_INSTALL_MEMLOCK Memory locking feature for passphrase locking *New with 9.7*
PGP_INSTALL_NETSHARE Netshare encryption
PGP_INSTALL_NOTES Email Encryption for Lotus Notes
PGP_INSTALL_SSO Single-Sign on feature for Whole Disk Encryption
PGP_INSTALL_VDISK PGP Virtual Disk *New with 9.7*
PGP_INSTALL_WDE PGP Whole Disk Encryption

In order to confirm the installation worked, the registry can be checked:


The “Value Data” associated to the PGP functionality on the right-side of the window should have a ‘0’. Changing the Value Data in the registry does not disable the functionality after installation has completed–this option only works during the installation.
