Vista - Homeworld 2 Installed but claims to have no DirectX 9b or greater!

Hi, I just got this game called Homeworld 2. It installs just fine but, then I get an error message saying that it has detected a DirectX program that does not meet the requirements for the game to function. So, it attempts to install DirectX 9, but then it says that the DirectX 9 installer detected a newer version of the DirectX that is already installed. So, I click the game icon, then get a black screen then it returns me back to my desktop. Is there any advice that someone can give me?

I love that game! I used to have it but the CD got corrupted and now I have to repurchase it.

Dude, see if you can right click on the game icon and click properties. Then click the Compatibility tab and check "Run this program in compatibility mode for Windows XP SP 2" click Apply then Okay. See if that works. If not hit me back.

I also remember reading somewhere that some games will not play in vista that were developed to use Direct x 9.0 because vista uses direct x 10.0 or whatever. So no matter what, some won't work, but I am wondering if that compatibility mode will allow it?

Let me know.

After questing for months, and months, and months... (you get the idea) I stumbled across this solution:

Disable DEP in Vista:

1. Click Start
2. Click All Programs
3. Click Accessories
4. Right Click on Command Prompt
5. Left click on Run as Administrator
6. Click the Allow button if it asks you for permission
7. Type or copy and paste this into the command prompt window:


bcdedit.exe /set {current} nx AlwaysOff

8. Hit enter and you should see the confirmation: Operation Completed Successfully
9. Reboot and DEP should be off.

I was a bit dubious that it would work, but it did.
