Vista - "run as administrator" box is greyed out???

I have a program that needs to be run as administrator. In the compatibility box the "Run as Administrator is greyed out and can't be clicked. Is this normal and how do I fix it???

I am the only user on the computer and an administrator. I am listed as the owner of the file already if that helps.

There are some commands, such as those the have the potential to compromise
memory, Kernal operations or other critical functions... which require full
(built-in) administrator. On Domain attached hosts this is even more likely,
requiring either Domain administrator or Enterprise administrator rights.

What does the program do? Is this a domain member host or stand alone? Is
your system subject to GP controls?

It is a game Beowulf. Although since I am an administrator I guess it runs all programs as such, so no need for the check box. At least thats what I gather from some sources I've glanced at since I posted. The game runs so either way it's all good.

As for GP controls and such, you went a little over my head with those. LOL. The game requires it to be run as XP SP 2 and is a peer to peer based game with the server only connecting during game for stats and vehicle respawning.
