There's no specific error.
And when I try to install manually (I've Administrator rights) he opens
Media Center with the message that he's installing. but then suddenly he says
he failed(no error) and automatically when I press OK runs System Restore.

Clearing the c:\windows\installer folder wouldn't help So I just put
everything back in.
Don't know how to solve
btw: some programs I try to install won't install either.
example: norton internet security 2005 and NOD32 (both no errors)

I've scanned for spyware found some and deleted ( www.hitmanpro.nl dutch).
But it has no effect
Any ideas?


ps. I've always the explorer in the mode he shows everything: hidden or not,
system or not don't like someone is hiding something for me
