I've created a DX application using the latest (Nov 2007) SDK and I want to know how I can get it to run on other people's computers when they are currently only running the standard DX9.0c. From what I've gathered so far, I need to supply them with the SDK redistributable files but a) I don't know how to go about this b) making them install these before they can run my application seems to be a longwinded pain in ass, is there a quicker way around this like say just including a few DLL's in my game folder? 

The EULA for the SDk does NOT allow you to redist the DLLs yourself for 2 reasons. 1. People generally don't like identical DLLs all over their hard drive 2. If they are duplicated eveywhere its hard for Ms to patch them in the event of a security issue.

So you have 2 choices

1. Ask your users to run the web setup - which will get all DX files up to date on the machine

2. Read the help file in the SDk about how to make an installer and include the CAB files from the SDK  http://msdn2.microsoft.com/en-us/library/bb174600(VS.85).aspx

Hi

Did you have any luck with this solution as I am having the same problem, and the help file link is quite confusing. Can anyone provide an easier to understand tutorial for DirectSetup?

What is your problem- the instructions are pretty easy. Include the CAB files you need and then make your installer call DSetup.exe as one of its final steps.

If your problem is writing an installer then this isn't the right place for the question.
