Windows XP Directx 9.0C problem !

[jaap1234]

I had a missing system DLL file in my Directx 9.0 C . I tried reinstalling 9.0C but I kept getting the same error over and over , missing system DLL file. So I decided to check with colleagues and on the Internet and Microsoft and found out that I needed to first REINSTALL the original directx 8.1 drivers from my Windows XP Home Edition cd.........but 1 needed file ( d3d8.dll) was not there which i really needed for my UNINSTALL/REINSTALL TOOL !

I tried to rollback my original directx 8.1 files from my Windows XP Home Edition cd ( the CD which came with my original DELL Dimension 8200 computer ) but I kept getting errors that the file d3d8.dll can not be found nor extracted



I was finally able ( after 8 hours searching, reinstalling, updating and rebooting ) to correctly download and install Directx 9.0B ( no dll errors ) via the game called RTW which had the dx 9.0b drivers included in their game, that worked !
But somehow I am not able anymore now to install DX 9.0C as planned. I can download the needed files from Micrsosoft but every time I unpack and try to install those drivers then the system sais SYSTEM UPDATED TO DIRECTX 9.0C but when I restart this is NOT viewable anywhere in the DX Diagnostics and only shows 9.0B installed .

Can anyone advise please what I can do now to really install dx 9.0c ? Do i really need to buy or download a GAME that has DX 9.0c and will that overwrite dx9.0b when installing that game ???

I'm guessing that you have some registry key still in place that is confusing your system.

It might be worth uninstalling it using this utility then trying 9c again:

Is this the tool you used at first to downgrade to dx8?

The program I used to uninstall my corrupt DX 9.0c files is called

DirectX Happy Uninstall V3.8.

But when I try to uninstall my current DX version I will get the message that I need to use the correct Microsoft Home Edition CD tried ( this CD came with my original DELL Dimension 8200 computer ) but I keep getting errors that the file d3d8.dll can not be found nor extracted from this CD so how can I then use this Uninstall tool if I cant even find this needed file ?


When I check the link sent by you it also mentions that after uninstalling directx I will need to install the original 8.1 DX files from my Windows CD, but there is the biggest problem > the Windows XP CD doesnt recognize this dammed file d3d8.dll so now I am afraid to use the Uninstaller. See attached text from Uninstaller tool >>

This uninstaller uses your original XP or .NET CD to restore your original DirectX 8 files.
Extract these files to C:\DXTEMP! You must extract these files to this directory and run
the UnDx9.bat that uninstalls the DIrectX files in SAFE MODE. Enjoy!
