So it was an optoin/parameter issue, not a Kix issue...

I must say that when typing Q321232 /?, the /R option is not documented as a possible option. All others listed by MartinD are. Didn't know there were "general" option that might or might not work with different update packages.

Since I don't think an immediate reboot is necessary for the update to be installed properly, the /R:N should do the trick. That option does suppress the "You must reboot..." question

Thanks to all for your help... [Smile]
