It was tough but I found it
I have three Blender versions in
AppData\Roaming\Blender Foundation\Blender\
- 2.92
- 2.93
- 3.0 (by installing Omniverse I had this folder generated. If you google search it Omniverse has been replacing Blender material graphs with omniverse material graphs which is an interesting approach)
I deleted 2.93 above and totally removed Blender 2.93 from pc.
I compressed 3.0 to uncompress it later.
Finally I installed Blender 2.92 and installed Speckle Blender 2.2.2.
Strange bug: By installing it in 2.92, I have also a 2.93 folder generated : 2.93\scripts\addons\bpy_speckle ??? I think I shouldn’t.
You should provide the option during installation to select to which Blender version, or to multiple version with a checkbox.
Best,
Dimitrios
