Terry, I’ve just repeated the installation on the Windows machine. I renamed C:\Users\my_user\AppData\Local\darktable to darktable.orig so it’s out of the way, and removed the cache C:\Users\my_user\AppData\Local\Microsoft\Windows\INetCache\darktable. When I launch darktable (which I installed from a ‘Windows Insider’ build), I immediately get the lue scripts installer. No need to download, clone, or edit anything.
If it’s not visible for you, can you check the preferences?
After I clicked the execute, it cloned the git repo, and then the script manager showed up:
Opening that allows me to install scripts as I already described in the post I quoted above.
