Thread Title:
Installation errors starting in the initial install from the CD and failure occurring during update after re installing my OS

Details:
I'll receive a number of "CRC Error: .... .DAT does not much" whenever I install. The actual files will vary each time I attempt to install. If I choose to ignore these errors during install I am able to the load the updater. The updater can successfully download the files, but when it begins to check and install the patch I'll receive errors: 20638 20641, and 20643 and the updater will close. Once I received Error: Catastrophic failure during install. I had the game successfully installed prior to re installing my OS.

Steps:
I've taken the following troubleshooting steps already:

Confirmed firmware and drivers are all updated.

Attempted install via the CD multiple times.

Burned disc image and attempted install via clone drive.

Obtained disk image from another disk and attempted install via clone drive.

My laptop has the game successfully installed, attempted to swap the contents of the /Program Files/Square Enix folder from my laptop to my desktop after installing (with errors) but before update. Received same errors from updater.
