Avogadro 2 won't let me set the Python version

Hello, I recently downloaded Avogadro 2, and I am having difficulty generating orca input files. I followed the advice provided in these previous threads to the best of my ability:

Orca input generator for Avogadro 2?

Hi, First off I’m excited about avo2, there is a ton of improvement over the first version, which is still very nice. I mainly use avogadro as an interface for orca, and the first version had a really handy input generator, albeit a little outdated, but it was a nice starting point. Is there an input generator for avo2? I downloaded the avogenerator extension from the program, but I don’t see one for orca. Has anyone out there made one that I can add? Thanks!

No worries about using a translator or English skills. It’s an international project! I don’t know what version of Avogadro you’re using or what OS. I’d first suggest installing a nightly build from https://two.avogadro.cc because it looks like a very old version and we’re about to release 1.100 soon. You do need to install Python to use many features. We use Python scripts for many of the input generator windows including Orca. If you let us know what OS you’re using, we can suggest how to g…

I am using a nightly version and downloaded miniforge as instructed but my Avogadro 2 won’t let me set the Python version. When I choose Extensions>Python Settings, I get this menu with no option besides “other…”

This happens before and after I download the input plugins. When I installed miniforge, I think I set it to be in the path so it would be visible to programs like this. Any advice would be helpful.

Environment Information

Avogadro version: 1.100.0-7-gac3f38f
Operating system and version: Windows 11

If it’s not showing anything, Avogadro can’t find miniforge in the path.

If you select “Other…” it should pop up a window to select a python.exe and go from there. Have you tried that?

Hey, Thank you for responding! Yes, I tried that and nothing happens

Hi there, I am having the same issue. When selecting other nothing appears. Have you managed to solve the issue? Thanks in advance.

Thanks for the reminder - let me take a look later today and see if I can get a test build on GitHub.

Is there any news on this?
I have Avogadro 2 installed on a separate drive (I, if that matters, on I:\AvogadroII\Avogadro2) and Miniforge3 on the C-drive (default location, C:\ProgramData\miniforge3).
As I write this, I checked one last thing, reinstalled just for my “main” user, into the folder C:\Users\Paul\miniforge3) AND had it add to the PATH, which the installation GUI of Miniforge3 strongly discourages, and then I was finally able to find it in Avogadro2.
Now, maybe this is obvious to other (computational) chemists, but if you’re stuck with this error like I was, maybe this helps?

Since I don’t use Windows, I haven’t had much time to sort this out - I’ve been working more on the optimization constraints and auto-optimize tool right now.

On the other hand, I do want to fix this (and make it easier to install python for new users) before the 1.101 release.

Clearly, the current release isn’t finding it outside of PATH on Windows.
