No such a switch for a MSI: /Reboot=Suppress. Use it without a slash. So, this is the correct line: /qn Reboot=Suppress For Daemon, this works for me: /qn Reboot=ReallySuppress This works, too: /qb REBOOT=Suppress If you have problems with 3.44, you'd better download 3.46! For .NET Framework 1.1, copy it from your CD to HD first, then install it from there. _______________________________________ I can't understand why people are using those /fs! Is there something in the registry to be overwritten?!
