In Vista DX10 and DX9 run side-by-side still allowing for the same compatibility with older games. Depending on who you talk to it's an attempt to get more Vista sales or an attempt to cut away legacy cruft from the DirectX API. All new versions of DirectX are capable of running older versions.ĭirectX 10 is the first version to break this convention. In addition a DX3 game would require 3 to 9. For practical purposes, Direct3D will refuse to run without hardware acceleration.ĭirectX 7 means a game requires DirectX 7 to 9.
In theory you could be able to use the software renderer, but AFAIK that is only permitted in games which link with DirectX debug builds (which are not part of the redistributable) and which are probably usually only useful for DEBUGGING anyway since they're going to be slow. Maybe someday we will have other types of virtualization-friendly hardware which would allow for stuff like DirectX but for now, nope). Post about the results in a more appropriate forum if you have problems.ĭirectX will be unable to use hardware acceleration (since that is not possible with emulated hardware, only the CPU is virtualized.
If it does not, go to Start > Run and run "dxdiag.exe" and check for errors or failed tests. After the installer finishes (and you reboot your computer if it asks you to) Orbiter should run. You must be connected to the internet when you run the installer. If you have trouble downloading the installer, use Internet Explorer to download it*.
Here is the DirectX Web Installer, which will automatically download and install the latest version of DirectX for your operating system. There is no reason why you should be trying to use an earlier version. However it sounds like you are looking for a solution to a non-problem.ĭirectX 9, the latest version for Windows XP, will run all games which require a lower version of DirectX, including Orbiter.
