run as aministrator

I have downloaded Office 2010 Beta successfully and am running on all profile

accounts. I am trying to open a calendar from another computer. I can only

open it when I am logged on as the administrator. It will not let me open

the file from the generic profile. I have right clicked on the icon looking

for the "run as" command and it is not there. There must be a Windows

setting that needs to be changed. I tried to set the permission in the

Windows XP "Secondary Logon Service" and the setup type is already set to

"Automatic".

I want to be able to run as administrator from my generic profile in order

to open the file in the generic account. Please help!
