That looks like a pretty munged up install, in terms of what's missing.
What I would suggest is:
1) If the steam version is also messed up, do a complete re-install there
2) Once the steam version is working well, copy the ai-war folder out of that to another directory outside steam
3) In the copy, delete the steam api dll
4) In the copy, run the AIWar exe
And it will run with no reference to steam, and presumably have all the assets intact
