OK, the file is writeable alright, but I keep getting the same error. Could this have something to do with IIS? I'm using a local installation btw. And I've set the permissions in IIS to be all writeable.
At the top of the page it shows this:
Warning: copy(../mainfile.php): failed to open stream: Permission denied in C:\Inetpub\webroot\kouyou\install\class\mainfilemanager.php on line 52
