I tried to install Outpost firewall for Vista x64, and the install was slow at best. Over ten minutes to get to the reboot option. Once rebooting, all I saw for the next hour was a black screen and a white mouse cursor. I gave up after an hour, rebooted to Safe Mode, removed Outpost, rebooted fine.
Tried installing the current Outpost Firewall Beta, same issue, black screen. Never could see the login page. Went to bed, over 8 hours, woke up to a black screen still.
Went to Safe Mode, and removed it, and haven't tried to install Outpost again.
I have tested and used Agnitum products before and stood by them. I still run TauScan on an external portable drive using Ceedo, even though Tauscan is expired.
I was really hoping to get Outpost Firewall to work in Vista x64. Have not tried Komodo yet. Trend Micro's version works, but not a fan of theirs, but works alongside Vista's built-in firewall.
Still hoping that ZoneLabs will get their stuff together and get an x64 version out. Since they been bought out and are no longer the original coders, I can see why they are struggling with x64 versions.
