This issue is caused by the connection order of Network Providers on the system. The Provider Order in the Advanced Settings of Network Connections determines how the system accesses information on the network. The
mpnotify.exe error occurs if the PGP Network Provider connection is listed below another third-party connection when using the Single Sign-On feature of PGP Whole Disk Encryption.
This issue has been corrected in versions of PGP Desktop 9.7 and above.
