Patcher error

I got the same error message saying it failed to write. I believe it was because I created the Grinding Gear Games/Path of Exile folder myself when I copied the files from another computer rather than letting the installer create the directory. Inspecting the files showed that write access for the Users group was restricted for many files, even if the "read only" box was unchecked in the Properties window. Upon changing the permissions for the Users group with the icacls command from the command prompt, I was able to patch correctly.

I'm running Windows 7 Ultimate edition.
