dplay.dll issues RRS feed

  • Question


    vista doesnt appear to come with dplay, i had issues running old games like doom, transport tycoon etc


    however i have found a solution in the windows/system32 dir there is a file called dplayx.dll


    the solution i found is to create a copy of the file and name it dplay.dll


    you should find this will solve your problem Big Smile


    hope this helps, chaosx

  • I have just encountered this same problem with Windows 7, that is, I cannot play the downloaded (via idsoftware.com) version of Ultimate DOOM I just payed 20 bucks for. I get the same message that DPLAY.dll is not found. I cannot reinstall it because I downloaded it online. Any suggestions would be appreciated.

  • How about Windows 7? and how do you access the dplayx.dll in windows/system32 dir Explorer tells me Search item not found! HELP!!!

  • Not sure if I am rehashing what others might have said, but I will run from the beginging just incase;


    I find the Autorun tends to fail install for any o/s after XP, so install the program (Setup.exe) with Admin priv and disable anti-virus.  For win7 users, you may also need to set compatibility made to Vista (no service packs).  If install fails, you may get a blank message box with a big red cross :)


    The setup should also ask if you wish to install directX v6.1, say yes since it can do no harm at all.  There are certain files which came in DirectX v6.1 (including DPLAY.DLL) as a final release, but regardless, you need to open a explorer window and find the DirectX directory on the installation source (i.e. the CD ROM).  Once there run the DXinfo.exe file to generate a list of installed and missing files, and unless your computer is from the stone ages and never seen a re-format, you will find 4 or 5 are listed as missing.  Now manually find these files on the installation source and do a copy and paste to the :\windows\system32\ directory, and if you run x64 you may need to use :\windows\sysWOW64\ (will not be harmful in anyway to put in both directories).  Although

    *Important* When copying, do NOT overwrite any file if the name already exists.

    Although you really only need to copy the dplay.dll, the others can help if you find the graphics are terrible.  Once complete, I would recommend doing a right-click/properties on the game shortcut and setting the compatibility to Vista with Admin priv.


    Hope this helps some of you who may still be having problems.

  • Hi. I read your post. I have windows 7 and I am having the same problem with installing Doom Collectors Edition. It says that it does not have the dplay.dll file. DO you have any advice on how to correct the problem? It would be grealty appreciated. By the way, I do not know how to get into the the windows/system32 dir. Thank you I appreciate it.

  • I found another way to get Ultimate Doom to work with Windows 7 if you have the disk. Put the disk in and install normally, then go to your DVD drive, open the DIRECTX folder, copy and paste DPLAY.DLL to whatever folder you installed to.

  • What about for windows 7. There is no dplayx.dll file.

  • I couldn't find dplayx.dll in Windows 7 at first either. What you do is open a Windows Explorer window and in the top right search box (should have "Search Computer" in italics) type "dplayx" and you should find it. I had two, in Windows\SysWOW64 directory and the other in a very long subfolder of the Windows\winsxs directory. Hope this helps.

  • This solution doesn't work at all for Master of Orion II on Windows 7. Help?

  • Hey, if you just got DOOM collectors edition or the doom+doom II+final doom etc or you still have it and just had a twinge of nostalgia, you should get Doomsday (it's free). It's a rebuild of the Doom engine using Quake III source code. It uses the data files and it's the exact same game, it just runs better on modern machines, has higher resolution options (same sprites and textures, just higher resolution and AA) and better controls, if you actually care for it.

    If you really (I can't imagine why) want to play it exactly the same, just without the bugs, you should still get doomsday and just set the resolution to 320x200, turn off the look up and down, and bind strafe to ',' and '.' and movement to the arrow keys. Cause original ultimate doom was before all this 1280x1024, WASD movement, look up and down stuff.

    No seriously, get Doomsday and you won't be disappointed.

    As for MOOII, the idea is simple. Install the game in dosbox as though you were on a DOS computer and the MOOII CD was in your CD drive. It will auto detect the sound card settings correctly unless you've actually messed with dosboxs sound stuff. Now run MOOII like you would on a computer from nineteen-eighty-I'm-still-young. Back then DOS programs installed with a program called 'install' and windows 95 programs installed with a program called 'setup'.
