Microsoft Application Virtualization 4.5 client service fails to start with Symantec PGP Installed


The Microsoft Application Virtualization Client service may fail to start on App-V 4.5 clients running on machines that also have Symantec PGP Desktop Corporate 10.1 or 9.x installed.  Attempting to start the service fails with the error:

Could not start the Application Virtualization Client service on Local Computer.
Error 1114: A dynamic link library (DLL) initialization routine failed.

A corresponding event will be logged: 

Event Type:        Error
Event Source:    Service Control Manager
Event Category:                None
Event ID:              7023
User:                     N/A
The Application Virtualization Client service terminated with the following error:
A dynamic link library (DLL) initialization routine failed.

In addition, sftlog.txt will show errors similar to the following:

[01/11/2011 08:12:56:691 INTF ERR] {tid=C10}
The Application Virtualization Client service cannot be initialized because it found an incompatible product (PGP Desktop version  No known compatible version exists.
This behavior is by design.  The App-V 4.5 client prevents a known issue where a Windows blue screen (STOP error) may occur if both the App-V client and Symantec PGP are installed on the same machine.  App-V fails to start the client service in order to prevent this scenario.
To allow coexistence of both the App-V client and Symantec PGP, upgrade the App-V client to version 4.6 or greater.
