Just made a comp for a mate, installed windows all good and everything.

Downloaded some programs such as Xfire and Ventrilo, they install fine.

I try to installed Bit Defender and Firefox and steam and it wont let me install them it crashes in the extracting stage with some weird errors like cabinet not right.
