Fix for Windows 11.

Error reads “Direct X 5 Not Found”. To fix, go into Windows file. Locate “comandos” run file and duplicate it. Rename this duplicated file to “commandos”. Right click on this renamed new file to get “Properties” then “Compatibility” then switch to “XP Service Pack 3”.
Reopen GOG. Right click on game thumbnail and click “Manage Installation” then “Configure” then “Features” then “Add Another Executable”. When searching, click on your new “commandos” file from earlier. Click to make it the default executable.
