I made the file an exception, specifically gave it the "allow" through the firewall and past the virus checker -- no go. Between my last Windows, drive, game and viral updates it doesn't want to play. Even turned off my incoming virus scan to see if that would work. The manual still hangs up.
I'll look into Whitelisting, but that seems to be run through the dev's website and has forms. It may take a few days to clear the time and it won't be an instant fix.
For now I'll just go back to II and wait for IV.
Shame, after a really difficult start up it had become my favorite 4X. Often opened it just to play with the ship designer.
Thanks for the information about the cause.
