[Wine] I need help running games on a mac

[MrWoody]

I am trying to run homeworld 2, and I am facing three problems:
I cannot install direct x because I do not have net framework
I cannot install net framework because I do not know.
I cannot get the auto run thingy to find the cd, neither the files I copied over, nor the cd drive.

I am running Mac OS X 10.5.8, wine 1.3.19, and I believe I tried installing net framework 2.

Anyone want to help?
