So I was farming on GW last night and I guess after I wa done and went to bed I left it running. I get up to find that there is a new build... so I close it out, and reopen it... theres a new update doohickey, and I was like "ummm... okay", then a message pops up that says:
"Unable To Install
The installer could not write Guild Wars to the specified directory. 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 have NEVER gotten this message before.
I only have one account to my computer, and I have 77.4 Gigs of space at the moment... what's the problem?

The Pointless
Have you actually bothered restarting Windows? In other words, shut down and fire up your comp again...

Yeah, that was the first thing I did
