I just got tropico 3 2 days ago its not working i get critacl error it says need dx9 video card but i have dx9 . my computer is a xp pro 2002

The video card in your pc likely does not meet the minimum system requirements to be able to play the game. The box will have these requirements on the bottom when you pick it up in the store usually.

What make/model of pc do you have?

dell de051

Alright so that has integrated Intel GMA950 video. This does not support Shader Model 3.0 and will not work for Tropico 3.

The good news is that computer does have a PCI Express slot in it. So you do have the option of purchasing a video card and putting that in which will allow you to play Tropico 3 as well as a lot of newer games.

If you are interested in doing that, here is a card that would run the game just fine.

can you download shader model 3.0?

I wish it were that easy

No, the video card in the computer has to support it. It's coded into the chip and your only option is going to be upgrading that pc with a new video card or buying a new pc. Or... Taking back Tropico 3
