COMODO Firewall cannot be initialized on my WinXP Home

I am installing COMODO Firewall Pro on WinXP home. I have tried 3.0.17 and 3.0.18.

After the installations, WinXP cannot be fully loaded. It stopped at the screen of WinXP’s logo with the flowing bar.

And I tried to start it in the mode of last proper setting. WinXP started, however, the firewall showed a warning in the status bar.

“COMODO Firewall Pro is being initialized…”

And after some time, it showed

“Network firewall is not functioning properly”

I ran diagnostics by clicking “Run Diagnostics”, it returned to the state that WinXP cannot be fully loaded.

Are there any special settings to make it works? Thanks.
