Issue/Introduction

When installing the Encryption Desktop client for Windows systems, using msiexec with the PGP_INSTALL_LSP=0 switch allows you to disable the LSP component. Please see article 171110 for details.

In some releases of Encryption Desktop, LSP is still enabled even when it is disabled with the msiexec switch and can cause conflicts with other applications.

Environment

Symantec Encryption Desktop 10.4.2 MP3, 10.4.2 MP4, 10.4.2 MP5 and 10.5.

Resolution

Upgrade to Encryption Desktop 10.5 MP1 or above.

If you cannot upgrade, please check with the third-party software vendors how to whitelist PGPlsp.dll or use the workaround described in article 153275.
