How to run Doom95 on Windows Vista/7

To be able to run Doom95 on Windows Vista or 7, you need to copy DPLAYX.DLL from the windows\system32 directory and place it in the doom95 directory and rename it to DPLAY.DLL.

Another method is to obtain a file named DPLAY.DLL. This file can be found inside the Doom95 installation archive in the DIRECTX folder. Another way to obtain the file is do download it separately via DLL-files.com. After you have the file, it should be moved over to the location of the Doom95 executable (doom95.exe). After this the game should launch normally.

Once you have downloaded the file, the screen will be in the top left corner of the screen with different colors. The patch to this glitch is to use the "-emulate" command line parameter. Alternatively, change the screen resolution to 640x480 Window and the game should run properly.

Note that on Windows 7, some screen resolutions are not supported, so you may have to use the supported screen resolutions for the game to work properly on the screen.
