You have not installed python so its not available.
Go to https://www.python.org/ and download python.
You may find that you want to get python version 3.11 (3.12 is very new and I do know if stable duffusion will work on 3.12).
You can find lots of good information about using python on windows here: 4. Using Python on Windows — Python 3.12.0 documentation
However if all you want to do is run stable diffusion I recommend using https://easydiffusion.github.io/ that takes the hard work out of getting it running.
Many thanks Mr. Barry for your kind reply.
I confirm you that I already installed Python 3.12 and got that message in the attached photo, and also I tried otner versions as 3.11 , 3.10 as you suggested and got the same launcher.
I am an architect Eng and just wanted to use AI in generating multi choices, but surprised how this is so complicated…I’m really frustrated because of this python un-launching.
Also could’nt use Python on Windows too.
Sorry, I’m just a beginner.
Then use the easy diffusion installer https://easydiffusion.github.io/
Getting stable diffusion running is hard for experts!
