"You have no access rights to install the application"

["You have no access rights to install the application"]

Got it working by changing users, don't understand why it wouldn't work on mine though, I am the main administrator.

Thanks for the quick response though

I am not using vista or 7, but can you explain how to get to "setup.exe"?

Hey,

I encounter this message every time I click the install button on the setup of Arma 2. I have searched the forums and have not found this problem occurring before. Can anyone help?
