Same thing happens to me when trying to install the game frome CD as the downloaded Demo.

I cant install the game - Gamefiles is copied and then hitting install would just make it say 25-40-100 install and nothing happens. After a restart of origin i have to put the CD′s back on and copy from the disc again but is just doesn work

intel I7-950
HD5870 1GB 13.2
SSD 128GB HDD
W764bit
Dustowizer

instead of using the disc just enter the redeem key into origin and see if that helps.

well it just says i need to download but i just installed from CD ? I cant give a key direct in origin.

I live in Denmark but have English W7 vistualizator - will try to go back to danish in windows 7

run your pc in safemode than install . Mine was stuck at 25% did that and it worked.

how do you do that ? safemode with network

without worked for me. it first said no connection but than it still installed somehow, i than reset my comp and booted it normaly and it was finished.

the problem was vistalizator
