Launching the ZPM Control Panel Applet on non-English XP results in the message
"An error has occurred whilst starting the control panel. The control panel will now exit."
The agent is non-functional, the event log contains entries such as:
AgentEngineApp::startAgent: Agent: An unknown exception was caught when the AgentThread constructor was run.
This is fixed in the 6.3 P-1 agent, version 126.96.36.1998, which is available for installation as a vulnerability from your ZPM server.
