So I was trying to install a game (Daggerfall - fully legit and legal, available free from the publisher).

I downloaded the files for dropbox, but there were errors with the extraction: it would not, or could not, extract "install.scr".



There is also a direct play version (i.e. without dos emulator). But when I try to install I have similar problems:

"C:\User\DAGGERFALL\INSTALL.SCR
An error occured while trying to rename a file in the destination directory: MoveFile failed, code 5. Access is denied
Press retry to retry"...etc., etc.

I checked on-line and read about trying as Administrator - I did that but it was exactly the same.

Any idea what could be causing my computer to dislike *.scr so vehemently?
(Also, I thought .scr was for screensavers, but it seems to be the extension for the install in this case - again this is a game direct from the publisher, not some random copy off the web).

Thanks in advance for any help.
