How to install Source SDK 2013 Multiplayer In this tutorial, I assume you have Garry's Mod as well as all the source games I have mentioned installed and also 7-Zip installed. That being said, since I published this guide almost a year ago, people have followed it and succeeded in installing it on many diffrent Windows versions including Windows 11. When it comes to specific versions there is none, I have personally tested it on Windows 10 Pro version 20H2 build 19042.928 and all the versions until Windows 10 Pro version 21H2 build 19044.1526 (being the newest version available in public channel as of time of writing this). Windows is required to run Hammer++, as other OSes are not fully supported by Valve thus hammer is not available for any other OS than Windows. No, but really I saw a lot of people struggling to install Hammer++ itself but they had more problems with installing it for Garry's Mod, so this is a way I found to make it work. How to use Hammer++ with Garry's Mod Why did I create this?
