After having to reformat my hard drive, I found my original CD for XP Pro SP2 was badly scratched (a cat). I had an older SP1 CD, used it, and upgraded to SP2 via Microsoft download. Since, I have been unable to install v 3 - had various issues and various error messages.
So I completely uninstalled it and went back to v 2.4 - all is fine. Then I tried to download the 32-bit v3, which after install gave me a message on many .exe files: Not a valid Win32 Application. Reinstalled v2.4 again, no problems. So I tried doing the Upgrade Patch. More error messages. Lastly I tried updating via the button in the v2.4 Control Panel - message says it cannot verify installation of Comodo Personal Firewall.
Before the reformat I was running Comodo v3, Avast Antivirus, SafeSurf, and Spybot with no problems. The only major difference is that I switched from Bellsouth DSL to Brighthouse DSL w/Ethernet Connection direct to cable. Until last week I was (with permission) using my neighbor’s Brighthouse Wi-Fi with Wireless Card.
Any ideas? I’d really like to be able to use v3 again.
