I'm using 5.6 and the editor wont open. The shaders work fine, but again, I can't edit anything or create anything with Shader Forge. Here's a recording of it not working.
Thanks for finding this out! This has been an issue for a very long time, and nobody had ever really found a consistent way to get Unity to download the correct one. I presume it works now?
So the asset store thought I had the latest version. I actually didn't have the latest version and Unity wouldn't let me update because it thought everything was up-to-date. I had to delete the local asset cache under C:\Users\XXX\AppData\Roaming\Unity\Asset Store-5.x so that I could update without Unity thinking I already had the most recent version installed.
Yea it works perfectly now :
