Ive had this Problem for awhile now, in being unable to properly install dx9c, however I have had great success in uninstalling it back to the original 8.1 version using DirectX happy Uninstall which can be found at http://www.mdgx.com/dx.htm#MDX (a DirectX unofficial support site. I believe the reason that 9c doesnt install properly on some machines is an actual video hardware conflict(card doesnt support DX9+) Hope this is of some use. Cheers

There are several tools to uninstall DirectX 9.0, such as DirectX Uninstall, Happy Uninstaller (uninstalls up to DX 9.0b only) and DirecX Erradicator. Just search the Google! This part is easy.

The real problem arrives when you want to re-install DirectX 9.0c again! Windows XP doesn't let you do it; it reports the necessary components are already in use, and they are! But, when you go to DXDIAG it reports Not Found, DirectX 8.0, 9.0 or 9.0b. So, why DXDIAG reports a different DX version? That's the Registry fault. So, all you have to do is to open Regedit (Start>Run>regedit) and look for HKLM/SOFTWARE/Microsoft/DirectX and replace the "version" key value to 04.09.0000.0904. That's it. Now, go to DXDIAG and check what's the reported DX version and click the Files tab to check if there are any problems. Good luck.

I can't install DirectX 9.0c. A message pops up during installation, saying "a cabinet file necessary for installation could not be trusted".

Hey. For those of you who are havint the problem with "A cabinet file cannot be trusted" heres what I did: I booted up from my Windows XP CD-Rom and i used the recovery console to do a chkdsk. I typed chkdsk /p and it said "chkdsk is performing additional repairs or recovery..." i then typed Exit to restart my computer, tryed re-installing DX 9.0c and it WORKED. Man I was getting pissed at that. Try it guys, hope it works for you!!!

safff

Yeah, I'm having the same problem with the untrustworthy cabinet. I cant play Underground 2 and its really pissing me off. i tried installing direct x from underground 2 cd and the microsoft site but i get the same problem every time. i dont have the XP disk, is there any other way to fix this problem?

Ive installed 9.0 from 7.1 and it just got worst my starfleet command game says i need to install 8.1, but ive already insatlled 9.0 it wont accept the settings and i cant play it.

So theres no way to go back to 9.0b?

Chiggz, I sure hope you still check this board! I'm going to e-mail you too, just to make sure you get this. Here is my question... I have tried to upgrade DX for awhile now from 9.0b to 9.0c, and it has never worked. I download it off the site, run the installation program, and it acts like it's going to work, but when I push "Next" to install, it just goes straight to the completion screen of the installation and says "The installed components are now ready for use.", but it wasn't installing anything at all. I've searched the web a lot for an answer to this problem, but have not found one. I thought maybe I actually do have 9.0c and that the Registry is messed up, like you said on your comment, so I tried putting in 04.09.0000.0904 in the version part of the Registry, but it seems like that version # is to 9.0b, so do you think it would work if I put in 9.0c's version #? If so, do you have that key value? Thanks for your time.
