I used to have an illegal Windows 7 on my computer, and as Ii got tired of the constant popups (not activated resolve online) I bought a legal issue and formated my computer.

Now every time I try to install it (both the 32 and 64 bit) it goes to about 2 or 3% of extracting files and then it stops with the message "windows 7 is unable to install, files are corrupt or missing"

So fix this and install Windows 7?

Since you now have a legal copy, call Microsoft. – martineau Jan 25 '11 at 11:42

Try changing out your dvd cd rom. I have this problem alot on systems that have an older dvd rom in it.

start from scratch !

flash the system after formatting, make sure you have the proper setup disk [ not the build ] and insert disk

if this fails, then you might have a hardware problem:

  1. check your cd/dvd player
  2. check harddrive.
  3. check memory.

Auch! This formatting hurts my eyes! – Ivo Flipse Jan 25 '11 at 13:01

Since you have a legal serial number, download a Windows 7 installation disk from internet, the same as you version (home, ultimate...) - but be careful to do not download modified one. Burn the new disk and retry.
