I believe this to be a bug with Avogadro:
Avogadro version:
Operating system and version:
Option to create an ORCA input should appear.
Available options only include APBS, CP2K, GAMESS, LAMMPS, or OpenMM Script.

What version were you using before? And did you install Python via 1.102 or did you already have Python installed?
Thanks
Oh, and there should be an Avogadro2.log file in your Documents directory. If you can post that, it would also be really helpful. Thanks.
Okay, I think this matches a bug report on GitHub:
opened 06:01AM - 28 Oct 25 UTC
**Avogadro version: (please complete the following information from the About bo… x):**
- Avogadrolibs: 1.102.1
- Qt: 6.9.3
**Desktop version: (please complete the following information):**
- OS: Linux Gentoo
- Compiler gcc-16
**Describe the bug**
Since 1.102.1, a fresh install with pixi installed (no files in .cache or .local related to Avogadro or pixi) doesn't show scripts from inputGenerators in the plugin list. Pixi-env needs to be setup with any new plugin installed from the download manager. This is annoying with package from distrib that provides this plugin by default.
Without pixi installed, all scripts from input Generators are shown in a fresh install.
There are two related bugs:
It should ask if you want to use pixi to run plugins and if so, create the default pixi environment.
If the default pixi environment doesn’t exist, it should just fall back to python by default
I should be able to spin up a build tonight to handle this case and I’ll post a link here for the Windows installer.
Okay, here’s the patch:

Okay, here’s a link to that Windows build (which I think should be the new “nightly build” soon). Should solve your problem.https://github.com/OpenChemistry/avogadrolibs/actions/runs/18893182107/artifacts/4400721911
