Why is Civ4 "No longer available"

[sub7th]

Just went to install Civ IV and I get this message
"Sid Meiers Civilization IV is not available on your current platform"

I was playing it last month.
XP Pro 32bit

What gives?

Nevermind. I'm an idiot.

Course No idea why steam would add 2 versions of the game to my list for the same PC. Really don't need the Mac version on my Windows Comp.

The Mac version of Steam allows you to filter the list and show only Mac games. I have no idea why they can't do this on Windows... but yeah you're not the first to fall over it.
