Hi,
I manage to install the generator 2.1.2 in animate2019 with the help of ZXPInstaller on OSX,
works fine (I’m pretty sure I tried on windows either)
for me the annoyng part is when only one document is open, each time you generate the template the window is reseted and empties all the fields in template generator
the simple solution is to have at least two document open all the time
