This command works correctly:
u3d install 2019.2.11f1 --installation_path "E:\Unity2019.2.11f1"
If I run the same command again it reinstalls it instead of saying it is already installed.
Also if I want to install a module in the same path later it is impossible for me.
u3d install 2019.2.11f1 -p Android --installation_path "E:\Unity2019.2.11f1"
I get the following error:
Please install Unity before any of its packages
I don't know if it's related to this other bug:
