Error 1603 when installing Comodo Internet Security

Hello, please help,
Uninstall Comodo Internet Security and decided to make a new clean installation, but the installation process to install the CIS can not get because I get the message “Unable to install Comodo Internet Security, Error 1603. Unrecoverable error during installation”.


¿ Could be a problem of my Windows Vista registry ?, Not to do, the only thing I can think of is to reinstall Windows. Anyone know the solution.

Thank you.

Give this cleanup tool a try:

Ok, L.A.R. Grizzly,

Fixed to the first problem, this program is perfect.

Thanks for the help. regards
