Update Error 106 in Comodo

Hello friends, I have a problem to install Comodo. When I try to install a Comodo personal firewall I get an error code 106 saying, that it cannot install the Comodo launch pad. When I press ok, another error comes up (003 this time) saying it’s going to roll back the installation and that I did not have privileges to install.
Can anyone help?

Comodo Launch Pad
Error Code 106: Unable to install Comodo Launch Pad!
OK
