[wpkg-users] Problem with Preshutdown

[d.guthmann at gmx.net]

Sorry for that HTML-%$&§ - my webmailer catched me :-(
Here again as Plain-Text:

Hello,
 
I'm using WPKG with Client-Version 1.3.14 for updating Windows7x64-Computers. wpkg.js is located on a network share.
WPKG is configured to run at shutdown-time.
Everything worked fine until we've updated to Firefox 37.0.2 - but I'm not shure if the Firefox-Version is part of the problem.
 
When I enable the wpkg-client-logging (I can observe the same behaviour in my Samba-Logfiles) I can see that the Firefox-Installation is startet via 
"Firefox Setup 37.0.2.exe -ms" and then the logfile ends abruptly. In the Windows Event Viewer I can find the following message:
Der Dienst WPKG Service konnte nach dem Empfang eines Preshutdown-Steuerelements nicht richtig heruntergefahren werden.
in english it would be:
The WPKG Service service did not shut down properly after receiving a preshutdown control.
 
Is that probably the reason? Did something in Windows7 changed (due to e.g. windows-updates) so WPKG can't do it's work at shutdown-time any longer?
Thans in advance.
 
Best Regards
Dieter
