I would strongly encourage whoever did the "here's how to go into admin mode" page to explain it in these terms. Key point being, the app DOES NOT need admin privs, and you SHOULD NOT use them -- instead, you should move the WoW folder. Document the admin thing as a workaround, but...
Won't somebody think of the people who have gotten five keyloggers so far this week? The primary market for this installer is EXACTLY the people who should not be told even that they CAN go into "administrator" mode, let alone how to!
So what is your OS, and for that matter what updater are you talking about (and what version)?
I am talking about the statement on the Curse page that the Curse Client requires administrator privileges.
I'm not using it. I'm commenting on why there is no way I would ever use it given that information. I'm off in Mac and Linux land writing my own code to scoop things off web sites.
I just thought I ought to point out that, in general, if a program requires administrator privileges, it is dangerous to run it. Not just because of any alleged risk from the program itself, mind. If you have to be logged in with administrator privileges to use the program, then every time you run it, you're running your computer in an unsafe state. The entire point of separating out administrator privileges is to make it so that ordinary operations cannot do dangerous things. If an ordinary operation requires special privileges, the privileges stop being special -- and the security is gone.
If you're on Vista then it's probably because Vista won't let non-admin mode programs actually update your addons because WoW installs into the Program Files folder by default, which is protected in some weird way.
I'm not on Vista, and don't plan to be.
But any time a program's manual says it needs admin privileges, I want either a detailed and cogent explanation of why it should need them, or a different program.
