Installation problems on dedicated server

If anyone could shed some light on this puzzler, I'd die happy.

I have multiple Windows 2003 servers, but only one that's beefy enough to run halo 2 dedicated server. However, whenever I try to install it, the installation fails with "installation of this application is not supported on your operating system."

BullCrap! I've already installed it on 2 other W2K3 servers. Trying to get this question answered puts you in an endless loop between Microsoft, Bungie, and Xbox.


Any help I would greatly appreciate.

You got it to work on other W2K3 servers? Really now, I thought it only worked on Vista. I hope someone can explain a way to get these servers up and running on W2K3 and XP, I'd love to host a dedi for map tests.

I've got it running on W2K3 too but you will need at least SP1, not sure if it will run on xp (readme says only vista and w2k3).
