oh, and remember, if anything goes wrong, you can still restore your system & blame your brother ;D
(you did create the restore point,didn’t you? 88) )
errrr, sorry but i’ve never checked my registry (regedit), perhaps other person could help
like i said, i create restore point,uninstall,reinstall. (:TNG)
and luckily i’ve never got any problem ;D
why don’t you just try it, reinstall CIS, and see if it works
