It's been a long time since I've used PlantUML, around 2019 was the last. I'm having trouble getting PlantUML_Template_v34 to work. I can't open the dotm at all. I've tried on two Windows 11 laptops. Refer screenshots in OneDrive link. I can see from other threads that v34, word 2016 will work, but I can't identify what is wrong with the setup I have. Asking for: help to either:
1. Suggestions on what I've missed in the set-up to get this to work, or
2. Other ways that I could make this work, i.e. can I use the source and create my own dotm?
