AntiSpam failed to install on xp pro

Dear Sir/Madam
I have installed, uninstalled and reinstalled AntiSpam a dozen time and still get the same error after booting: failed setting up Comodo antispam 2005. I read one of the post having the same problem, but it involve an incompatibility between antispam and antivirus.
presently I am using:
Comodo Fire wall, Avast antivirus, BOClean, my email client is Becky!.
I tried installing after disabling Comodo firewall and BOClean, still with no joy. Any help is very welcome.
Thank you in advance for your time.
Kind regards

I had the same problem, except I used different programs CPF, Windows Defender and Avira (could not make internet work with CAVS). It could not locate some .exe file! Try installing it in save mode, it may work!
