I have this slight problem, and I see resolutions to it but they do not apply to me, see whats going on is I get the “This is an older version of comodo firewall pro, go to comodo.com and get the latest version” message, and I see the solutions of removing the old software then installing, BUT I just installed Vista on my machine as a clean install, no prior software installed, any suggestions?
Yes, I too am getting this message. New Clean Vista as well.
G’day,
CFP V3.X had a time limit on when it could be installed. If you temporarily set your system clock to a date earlier than July 27th, you should be able to install. After installing, you can change the clock back to the correct date and the firewall will still operate without a problem.
Hope this helps,

P.S. Next development release is due on August 16th. Whether it’s another alpha or is released as a beta is yet to be seen.
