Right at the top, stickied thread:

http://www.gamesas.com/topic/1258133-installing-from-disc-instead-of-steam/

i have tried that but when i right click on library nothing there

Skip that bit. Just do the rest.

followed that but i dont understand the replace c bit if steem isnty in proram files,its in program files(x86)

It means change the locations of the steam folder, and the letter of your Drives, to whatever is on your PC. Not everyone's is the same.

but steam is on my c drive in program files (x86)

try running a registry cleaner like ccleaner and then installing Oblivion gave me the same issues back in the day...bad uninstall left registry strings behind that prevented a reinstall. Just don't clean your whole thing with CCleaner and then come on her crying about your cookies etc. Use the registry tab only and make a backup when prompted.

what are you going on about

Then put the full file path in for your pc. For example, I changed the one in the guide to this for me:
C:\Games\Steam

ive now got C:\\games\steam\steam.exe"-install D but it still wont work

please help

If you can't follow the instructions were giving you, then how can we help? We're trying.
