Guys I need some REAL help, I'm trying to install our Technet DVDs onto our
IT support department PCs, when I put the disk in and ask for the English
only option it either says that I need to be logged in as a local admin in
order to modify all profiles - even though I am logged in as the local admin.

OR, it gets as far as the installshield and just comes up saying that the
installation was interrupted and nothing was modified, I've tried looking for
help on the internet, but the only things I've come across are things like
"...If you're having trouble installing an application, refer to Technet..."

But how do I refer to Technet if the application I'm having trouble
installing IS Technet!!
