Welcome to the ZDoom Forums!

It seems that on the download page https://github.com/ZDoom/gzdoom/release ... indows.zip, the windows version doesn't include WSOCK32.dll. Then when trying to run the gzdoom.exe i would get an error saying that the WSOCK32.dll is missing.

Downloading the WSOCK32.dll manually from some site like https://www.dll-files.com/wsock32.dll.html and moving it to the GZDOOM folder did work. Please have a look to the missing .dll so that it gets included in the download.

You don't need WSOCK32.dll. It should be included with windows. Y wenas.

Oh oke, thanks! For some reason the .dll was removed from the system32 folder. Added the WSOCK32.dll in the system32 folder and now it works properly without needing to past the .dll in the GZDOOM directory.

First of all - that site you linked should positively never be used to find replacement .dll files - much too often, that site, and many others like it, are used to spread malicious files that can compromise your system and steal your information.

Second of all - wsock32.dll is a system component that has been included directly in every version of Windows since NT 3.1 and Windows 95, the earlier versions of which required a special "TCP/IP" component installed in the system's networking panel. Missing that is a critical failure of your system, and you should do an integrity check to ensure that you have other critical components of your system installed. Not having it likely indicates either the correct components are not installed (which is not possible since around Windows 2000 or so) or your system has indeed been compromised.

For what it's worth (not much really - Rachael's information is the important stuff), my wsock32.dll (Windows 10) isn't in system32; it's here:

Edit:
Actually, forget that. A better search reveals 4 copies of a file with that name in various locations including system32, and a few different versions. It looks like the copies might be different versioning backups etc.
