Dear 
granpa,
Sorry for posting this on the forum (and posting it to the public too...), but I noticed your post here, and wondered if it was possible to make it work on Windows 11, without admin. I have DirectX installed, but it came with the computer (or our school installed it), is the version 12, and I don't know if it does work with Construct or not. When I launch the Construct Classic executable, it appears in the task manager, but no windows open.
It doesn't work on Windows 10, where the regular Construct Classic is installed, and working, but the one you made shows an error saying it can't start
