Downloading problem - Runtime Error!

I can’t install Comodo, I get the following message:

Runtime Error!

Program:…CONTENT.IE5\4Z4RK5SX\CFP_SETUP_ENGLISH_2.4.18.184[1].EXE

This application has requested the Runtime to terminate it in an unusual way. Please contact the applications’s support team for more information.

Please help!

I should note that I have Windows 98 SE.

Thanks (:SAD)

Sorry befuddled but the firewall is only compatible with the following systems:

Windows 2000 (32 bit ALL)
Windows XP (32 bit ALL)
Windows 2003 (32 bit ALL)
