When i try to connect i get this msg:

Unable to install
The installer could not write Guild Wars to the specified diretory. Please check that you have administrative access, that you have permission to install programs in the specified directory, and that there is sufficient space available on the drive.

I checked and it should be able to open, but won't. any suggestions?
