Hello, I just bought Thaluna and I'm having trouble starting it.

It displays an error message saying it can't find the model, even though it's definitely there.

Thaluna version: latest Stable

version: Windows 11

What's happening? I can't even launch the tool; it crashes immediately on startup with the following error message.

Hi!

This is caused by the folder path containing accented / non-ASCII characters, for example "Téléchargements".

I was able to reproduce the exact same error on my side — the model files are present, but the loader fails when the app is located in such a path.

Please try this:

Move the whole extracted Thaluna folder to a simple path such as: C:\Thaluna or D:\Apps\Thaluna\

Then run Thaluna.exe again from that folder.

This should fix the issue immediately.

I’ll also improve this behavior in a future update so the app handles this case more gracefully
