Admin Control problem

Hello all.

I have searched the forums the last hour or so and havn't yet found a solution to my problem, hoping it hasn't been asked elsewhere but here goes..

I am trying to install world of warcraft... the first game install's fine, then when I try and update it - an error occurs saying I dont have administrator access - so it wont go any further. When I click 'more information' I get

'Administrator access required to install the game.
This program requires administrator access to be installed. If you do not have access to an administrator account on this machine, please contact someone who can log on as an administrator to install this program. Non-administrator accounts are not able to install the files which are required by this program. If you do not know what an administrator account is, or you need help logging on as an administrator, please contact your local computer manufacturer for more details. '

I have checked and rechecked... I have full admin access on my profile, I made another profile and gave it admin access, still the same problem.

Any suggestions?

Cheers.

Right click the update and select "run as administrator"

Thanks very much
