I am trying to load the drivers for a BT Voyager 105 DSL Modem to install AOL onto a Win XP Pro PC

 I have loaded these numerous times on my own machine (XP Home)

It keeps saying 'Error Loading newdev.dll', then tells me I need Administrative Priveleges to install DSL drivers.

I have only 1 user created who is created as an administrator so I don't see where this problem is coming from.

Any ideas???
