Comodo Firewall won't install

I currently have Comodo Firewall 3.5.57173.439 installed on a XP SP3 32 bit system with Kaspersky antivirus. I manually downloaded Comodo Internet Security version -3.8.64739.471 and nothing happens when I try to install it. I answered Yes to Add/Remove components, then selected the firewall only and clicked OK. The window went away and nothing happened. I ran a task manager and found that there wasn’t any installer working in the background. I attempted the install with background task disabled, and tried it after a reboot. Same thing, just exits without saying anything…

What happens when you uninstall Comodo firewall first and then try running the installer? You can use this tutorial for Comodo Firewall; I think it would work with CIS as well: https://forums.comodo.com/help_for_v3/comprehensive_instructions_for_completely_removing_comodo_firewall_pro_3_info-t17220.0.html .
