Command line option syntax error, after install.

[DurerKleinst]

Whenever I try to install 7zip,during RunOnceEx and after everything has been installed( i.e. normal windows session), the installer gives me the Command Line Option Syntax Error and tells me to use /? for help. The odd thing about this is that I'm not using any CLOs. I simply try to install it normally by opening the file.

However 7zip isn't the only one doing it. My HP printer software does the same, allthough since it's an MSI installer, it says it differently. Also doing it, as my father tells me, is Corel WordPerfect 7 or 8, however I have yet to verify this myself. I also suspect the root of this problem affecting Norton SystemWorks 2003 by doing something to the LiveUpdate and Cleansweep installs, however it doesn't say invalid CLO it says error -12. However, it doesn't effect NSW 2004.

Another problem I'm having is with a few certain programs, right now I can only remember the nForce installation, it says "Can't find C:\Doumen~1\", or something like that. Could this also be related?
