I'm trying to use the DMView for the first time for an ERCOT project and I'm not able to install openpyxl. I get the following error messages when I try. I've experimented with using pip, pip3, and pip3.7. The issue is the same using pip as opposed to pip3. The last one is not recognized.

I set the python path in the 'run3x.bat' file explicitly. Does 'openpyxl-3.1.2-py2.py3-none-any.whl' have to be somewhere specific? After I downloaded it, I put a copy in my DMView folder and another copy in "C:\Python37\Lib\ensurepip_bundled" Does it need to be somewhere else?
