For those of you experiencing problems installing Bridge Commander on Windows 7 SP1 x64.
I found a solution.
Its not perfect, but a solution nevertheless.
As you know, I was unable to install the game. I ran the installer, tried to run it as admin, in various compatibility modes, even left the laptop on after running the installer over night, and nothing (I could see the process in Task Manager, but ultimately, there was no installation going on).
Anyway, I downloaded the 'core' of BC off the net, which is roughly 350mb.
It's essentially the install directory of the game.
Has all of the animations, dialogue, scripts... its a full game, and works on my system nicely.
Now I just want to play around with mods.
