abacus23,
     Before trying to copy the the disk to your hard drive, lets try a couple other things first. 
I just realized that you never completed the steps from KB928080 about error 1722.  Lets startwith completing that.
If you were able to download it and run it properly then you will have a folder called "MicrosoftKB928080" located on your C: drive. 
First thing to do is verify that folder does exist. 
Click on Start > My Computer > double-click on Local Disk C:
You should see the folder MicrosoftKB928080



If you don't, you need to follow the instructions from KB928080 to make sure you have downloaded it and run the initial setup.
Once you verify that the folder is there then open up a Command Prompt window and type the following command and press enter:
c:\microsoftkb928080\resetsldl -All
The only space is after resetsldl.  The command should run and give you a result



After you complete this and get the result as above then try to re-install the game.
Let us know the results of that.
