KernelEx release 4.5 Final

Steam is a digital distribution, digital rights management, multiplayer and communications platform developed by Valve Corporation. It is used to distribute games and related media online, from small independent developers to larger software houses. Steam also has community features, automated game updates, and in-game voice and chat functionality.


To install Steam on Windows 98 you have to use an old .exe installer (downloadable here). After that you will get an update window that will disappear. Now you have to make sure the task is gone, and disable all KernelEx extensions. Double click Steam and wait for it to update. You will get a message saying that the Operating System is not supported. Click No. Set KernelEx to Windows Vista. It will update with the new user interface. You will lastly get an error message:

"Steam.exe (main exception): Unable to start Steam Engine: *SteamSTartEngine(0x76e840) failed with error 1: Failed to create pipe: 120, Win32 Error 120 "This function is only valid in Win32 mode."

This means that not much else is left to get it working, but so far this has not happened.


This was tested with RevolutionPack 9.7, Autopatcher December 2008 and 98SE2ME installed, so some of this might be necessary to get as far as here.

It has been noticed that most games offered on the Steam platform work fine on Windows 98 SE as Steam-less versions.
