I'm looking for a Samsung Windows 7 OEM DVD (preferably Professional/Ultimate).

Mate asked me to sort his laptop, I used the 48 in 1 DVD, but 7x64 fails to update, and 7x86 installs and seems to run fine, but a few apps I've installed won't run so I want to try again with a proper Samsung DVD, but I've been looking around on the net and can't find one yet
