So I have 64-bit Windows 11, NVIDIA GEFORCE, and it took me a while to get the game to work. I will post what I did, in case it helps others (and in case i ever have to reinstall it myself :D). I updated (via notepad) the files per nikale21's post (steps 4 & 5), but I did not do the DXGL install; instead I did the following: Added the 3 files from the following link into the game's exe folder: https://github.com/elishacloud/dxwrapper/wiki/The-Settlers-IV (you can also put the editor files from the above github link into the editor folder to fix that as well) Then added the 5 files for WidescreenFix.zip from the following link into the game's exe folder: https://github.com/zocker-160/Settlers-IV-Patches/releases Many thanks to those who have helped create/update these files to make gameplay possible in 2024!
