Still no luck. I agree, it's a little odd that I can't open the folder from the install screen, but I can when I'm using the computer normally.
The file is there, as shown in this screenshot: http://i.imgur.com/Uwum5fz.png
Thanks again for all the help! At least I learned a little! If you ever figure out the solution or get a new idea, just PM me or post here again.
Thanks!
