I’ve gotten different errors each time I try to run the installer. The first time the installer couldn’t shut down Outlook and Windows Explorer. Then it couldn’t access epfwlog.dat. I restarted and got past the shutdown issues but it still couldn’t access epfwlog.dat. One more try and it couldn’t access cache.ndb. The failed instal seems to put version 3 back correctly, although the GUI is disabled. I'm running Smart Security 3 on Vista Ultimate SP1 (32 bit). Suggestions?
