Hi All,
I'm trying to install the UNTOOLS v2.5 in ArcGIS Pro 2.5 by following the steps to install UNTOOLS described in the below link:
Install the Utility Network Package Tools toolbox—Get Started | ArcGIS Solutions for Electric
After cloning the default Python environment (and re-starting ArcGIS Pro), in the Python Package Manger, I attempted to install UNTOOLS 2.5.

The installation run without errors; however, after re-opening ArcGIS Pro, I could not see the Utility Network Package Tools toobox in the Catalog window:

In addition to that, UNTOOLS 2.5. does not appear in the Installed Packages list:

I'm not sure what's causing that. Any help would be appreciated.
Thanks
