Hi Mark,
Thanks for letting us know -- can you tell me, does it show that error immediately, or is that error shown after the install process gets started? Can you tell me what version of windows you are on? XP, Vista, (and by extension Windows 7) are the OSes supported.
You might try updating to Windows Installer 4.5 (free update from Microsoft), since that will often fix any problems with MSI package installation (our product is actually in an MSI package wrapped in the exe that checks prerequisites). Here's the link for that:

http://www.arcengames.com/share/AIWar1004Full.zipUnzip the above to anywhere you want, and you should be able to run it as long as you have the prerequisites installed:
Microsft .NET 2.5 Framework SP1:

http://www.arcengames.com/dl/dxwebsetup.exeMarch 2009 SlimDX Runtime SP1:
http://www.arcengames.com/dl/SlimDX%20Runtime%20(March%202009%20SP1).msiAll of the above are normally installed by our installer, but if you can't run the installer then you have to do those yourself.
Once you have all that down, you'll be able to run 1.004 of the game. If you want 1.005, you can download this:
http://www.arcengames.com/share/AIWar1005.zipThen just unpack it on top of the 1.004 version, and you'll be at full 1.005.
Just as an FYI, if you install the game like this without using our installer, then future patches will not work (they are based on the same MSI system as the installer, and require that the installer have first succeeded). However, I tend to make the zip files for updates available for those who have trouble -- sometimes the windows installer components on a person's machine are just corrupt in some way that prevents more modern-style MSI packages from being run. The other alternative would be to buy the game through Impulse, if you find yourself purchase-inclined -- their installation and patch distribution system does not use windows installer or MSI.
Thanks for your interest in the game, and please let me know if there's anything else we can do to assist.
Best,
Chris
