Unable to install pythonnet clr module by uninstalling clr and re-installing clr

Question

I am trying to import clr and receive the following error:

AttributeError: module 'clr' has no attribute 'AddReference'

I have tried to follow the steps here, where I uninstalled both pythonnet and clr, and then install pythonnet and then clr.

However, I still get the same error.

I'm using spyder 5.4.1 (on a virtual Windows machine).

Any help is greatly appreciated!
