Cannot Install latest Free Firewall XP

I am using XP sp3 Cannot Install latest Free Firewall .There is no error, files are extracted but not installed.
I am having similar experiences with other firewall vendors. I think XP is no longer supported.
Any ideas,

see if windows do not allow it

The system requirements for version 7 on the Comodo help site for Windows XP is as follows:-

Windows XP (Both 32-bit and 64-bit versions) 

256 MB available RAM

210 MB hard disk space for both 32-bit and 64-bit versions

Internet Explorer Version 5.1 or above

Try using CCleaner to clean temporary files and fix the registry.
Then try to check if your machine does not have any malicious software that is blocking the installation, you can use (Comodo Cleaning Essentials and HitmanPro).
