I purchased the boxed retail copy of Empire: Total War yesterday and am getting nowhere with the installation process. When I try to install, either from the DVD-ROM's autoplay or through the command line "c:\program files\Valve\Steam\steam.exe -install E:", I get only as far as the window that says "Creating local game cache files" and "Preparing files for install". The progress bar gradually fills up to 100%, but stays there for hours at a time (I even left it overnight) with no activity from my DVD drive, and no apparent network activity. Canceling the installation causes Steam to freeze completely, and can only be closed through Windows task manager as a Non-Responsive program.
Solutions I have already attempted, to no obvious effect:
-Deleting clientregistry.blob
-Closing out all antivirus and firewall software
-Trying in offline mode (makes installation impossible, near as I can tell)
I have previously installed 9 other games through steam, including all games on the Orange Box, with no problems, and can confirm that I meet or exceed all minimum system requirements, including hard drive space.
Your help would be much appreciated!
