I just installed GhostWall 1.150 on a Windows Server 2003 x64 Enterprise. Setup terminate without any kind of problem, but executing GhostWall I got following error sequence: 1) Error creating ghstwall.fir in system32 folder. This is the default ruleset of GhostWall 2) Error creating GhostWall firewall driver. Without this driver GhostWall cannot protect you. I think the cause is some Windows Server security feature that blocks \system32 folder. Please, help. Thank you in advance.
