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

hotfixHere’s another new KB article we published today. This one involves a conflict between App-V 4.5 and PGP:

=====

Symptoms

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:

 

---------------------------

Services

---------------------------

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

Description:

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 10.2.0.1672). No known compatible version exists.

Cause

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.

Resolution

To allow coexistence of both the App-V client and Symantec PGP, upgrade the App-V client to version 4.6 or greater.
