Oh.. you tried to move the files
? The dialogue box is right, you can't do that.
How about just copying them
Select all the files on the disc by going to the disc window, pressing Ctrl-A to highlight all the files, then Ctrl-C to copy, followed by Ctrl-V in your target destination window...
Moving files from a Read-Only source like CD or a DVD
is obviously impossible but copying them should be possible unless your installation media has been scracthed or deformed..
Also can you check your DEP (Data execution Prevention) settings
for me and post a screenshot of that too, apparently there are issues with getting the installer to run properly under certain DEP settings
Go to start
