Cis 5.8 installation

After downloading CIS, I get fatal error 1603 everytime I try to install. Im running win 7 64 bit. Cannot install any version of CIS. Has always worked flawlessly before with win 7 64 bit. Ok on 10/17 I went and deleted the old registry keys for the old installation and all’s well!

Please trying reinstalling it using the advice given in this post and let us know if you still have problems.

Your problem could be due to problems from a previous installation.
