Windows XP SP2 install, stops at “Checking Product key”
Then I found the solution (thanks Ste123) on a Microsoft forum of all places and here it is. Naturally, use it at your own risk.
1) Open a CMD prompt
2) Then type cd /d %windir%\inf
3) Then type ren oem*.inf oem*.old
4) Then type ren oem*.pnf oem*.old1
5) Then find the file by name INFCACHE.1 and remove it from the inf directory
6) Close all windows and reboot the computer to safe mode and
start the installation of SP2 and it should go fine
Thanks to STE123
