this appl has failed sart because spwizeng dll was not

i just got my DVD from Microsoft, i loaded it into the dvd drive, and this message came up:
"This application has failed to sart because SPWIZENG.DLL was not found. Re-installing the application may fix this problem"
i hit ok, and i get a second error, it reads:
"the file 'autorun.dll' could not be loaded or is corrupt. Setup cannot continue. Error code is [0x7E]"
i then ripped the dvd onto a new file on my desktop, then ran it again. the same thing happened, and that took 30 minutes, i am now on my 3rd hour trying to get this $10 beta to work that i ordered a week ago, anyone can help, it would be great, and it isnt my computer, i had to buy another 1 gb of ram and a 512 mb vid card to play Battlefield 2, that cost me $500, my compuer is up to date and fast, i have windows xp, i have not had any problems installing any software or hardware. oh, after i hit ok, on the second error, everything goes back to the beginning, i have tried 5 times now,
anyone had this problem?
