You can't. NT4 SP3 to SP6 came with DirectX v3. To use higher version you have to install either Windows 98, Me, 2000, or XP.
 
You can play OpenGL games on NT4 just not DX ones.
 
 

I have not seen a single issue of DX for NT4 since v3. If there was one it was a hack. No NT4 drivers will come with DX support anyway.
 
DX 5 was designed for Windows 95/98 and due to come with NT 5 (renamed Windows 2000) but eventually came with DX 7.

If anyone has Dx6 for NT4 PLEASE!!! send it to me:
elwis1007@wp.pl
I can`t live without it!.
 
Thanks for response.

LOL. As far as I know there never was a DX6 for NT4. Now there is a SETDX6 program which will change the DX3/5 version of your NT4 directx files to fool programs into thinking that DX6.1 was installed. But that's it. There is no DX6 for NT4.
 
The program is here: http://vogons.zetafleet.com/viewtopic.php?p=42641#42641
 
You may have to register with the site to download.
 
Don't ask me any questions about the program since I haven't used it in about 5+ years.
 
 
The following is from the readme.txt that comes with the file:

You know this problem:
"This game need a newer version of Directx"
 
The solution:

What does SetDX 6?
----------------

Lets fool some games a little
-----------------------------
Create a temporary directory and extract setdx6 there.
 
You need the follow files from the system32 directory:
d3dhalf.dll
d3drg16f.dll
d3drg24f.dll
d3drg32f.dll
d3drg8f.dll
d3drgbf.dll
d3dxof.dll
d3drm.dll
d3drm16f.dll
d3drm24f.dll
d3drm32f.dll
d3drm8f.dll
d3dxof.dll
ddhelp.exe
ddraw.dll
dinput.dll
dsound.dll
 
copy the files also to this temporary directory.
 
Make sure that the files are not write protect.
If you get a DDRAW.DLL file in use or DDRAW.EXE file in use,
go to task manager and kill the application DDRAW.EXE before.
 
Run setdx6.exe
 
Copy the .dlls back to system32
Copy the automatical generated sound.vxd (for Lucasarts games)
also to system32
 
Add the regkey (regedit.exe): HKLM\Software\Microsoft\DirectX\
Value: Version, Regtype: REG_SZ, String: 4.6.1.0
 
Restart.
 
Tips
----
1) Backup the .dll before you run SetDX 6
Keep in mind this is a early beta.
2) SP4 content dplay 6.1
Download SP4, if you don´t have it
3) NT 4.0 compatible games
An excellent listing of NT compatible games is on

Sorry for my English but I`m from Poland
Hmm....
If Dx5(from beta1 2000) works on nt4... maybe DX6 from Beta2 Win2000 works on NT4.
 
dsound.dll from DX7(for 2000) work on NT4 (I checked this)
 
I want only run one library - ddraw.dll version Dx6 - nothing else.
 
I look for SHS on Google and Altavista but I don`t find anything special.

I hope it exist somewhere in side cyberspace.
 
 

Anybody find a DirectX6 for NT4?

Quote:
Windows NT shipped with DirectX 2.0. Upgrading to Windows NT 4.0 service pack 3.0 will install DirectX 3.0. However there are no higher versions of DirectX available for Windows NT. Installing Service Pack 4 or higher will install later versions of DirectPlay however.

Time to upgrade OS?

If anybody wants a USB, FAT32 or DX5(with DPlay6) for NT4 please contact with me: czarnylewis@wp.pl.
 
 

I wanted to contact with SHS (Anthony Toste) but i don`t know his e-mail.
