Problem with the Atomium instalation on windows?

I get the error below when trying to import a pdb-file, online or localy.

I have followed the steps in the instalation guide: I run Blender as an administrator on Windows 10, and after installing the add-on, i click the button to install Atomium. I get a confirmation that Atomium is successfully installed.

In the MolecularNodes panel i click the “Download” / “Open” button and get the error below. I assume the it is because the Atomium library is not properly installed.

Python: Traceback (most recent call last):
  File "C:\Users\Jonas\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\molecular_nodes\__init__.py", line 1401, in execute
    sna_func_import_structure_EE5B6(bpy.context.scene.sna_pdb_code,
  File "C:\Users\Jonas\AppData\Roaming\Blender Foundation\Blender\3.1\scripts\addons\molecular_nodes\__init__.py", line 1134, in sna_func_import_structure_EE5B6
    pdb = atomium.fetch(pdb_id)
UnboundLocalError: local variable 'atomium' referenced before assignment

I am very curious to try this amazing add-on, hope that you can help resolve the issue.

0.3.8 release worked for me aswell, and probably there is no need to run Blender as administrator.

Success 😃 The 0.3.8 release of the add-on resolves the issue. At least on my Windows 10 installation. I removed the old version of the add-on in Blender. Restarted as administrator, and installed version 0.3.8 of the add-on, following the normal procedure. After that I was able to download pdb-files. Opening local files also works. Running Blender as a regular user afterwards also works.

Do we now have Atomium installed two places, or is the add-on just loading Atomium from the other install location?
