I have the same problem. None of my programs will execute. Has anyone found the solution??? I also noticed that since the update the Window’s Operating System is being blocked by the firewall. I’ve been unable to find out why.
I am also running Vista 64 bit, and had same problem after updating the firewall - couldn’t run any programs. Only help I can offer is that after going back to the last restore point before I installed the update, everything worked fine.
I tried installing again, same problem, went back to a restore point, everything OK.
I won’t try to update again untill I see some solvable explanation.
