I got it working on Linux. It’s a bit involved though (Ubuntu) based:
- Get
linux-64/pythonocc-core-7.4.1-py37h2700f40_0.tar.bz2fromhttps://anaconda.org/conda-forge/pythonocc-core/files - Install the 1.0 version of STEPper into Blender 2.92 in Linux, but don’t enable it
- Inside the Blender addon folder, replace the OCC folder with the one from the downloaded conda-forge archive
- Install occt-draw version 7.4 from apt, as it will also pull all the required libraries for the addon.
I’m using Linux Mint, so I had to adddeb http://archive.ubuntu.com/ubuntu/ groovy main restricted universe multiverseinto additional repositories in software sources, then usesudo apt-get install -t groovy occt-drawmake sure it’s version 7.4+
Not going to take responsibility of horribly breaking your system 
Python versions have to match. The required OCC version must be 7.4.
This is probably as simple as it’s ever going to get, unless I’m going to compile a fat executable at some point in the future, which is unlikely.
@rally037 It might, but there’s no support for it. As far as I know both Blender and Microsoft have stopped (or will soon) updates. You will probably get missing DLLs (don’t work).
