Hi i was trying out your firewall (freeware version) on a winXP 64bit sp2 computer because my current firewall vendor doesn't support 64bit systems. At the end of the installation, I was asked me to provide the location of a system file (sorry, can't remember: it was something like OAxxxx.sys) The file was not found anywhere on my computer. I tried to removed it but I couldn't find online armor in the add/remove settings, so I tried to install again. the same problem persisted. eventually i removed any files. Have I done something wrong?
