Cant install new package via CONDA?

[SimonJackson]

• Pro 2.2.1 (upgraded from prior versions).
• Trying to install Selenium 
• Pro interface, options, python, dont seem to be able to install new packages (greyed out)
• Resorted to firing up proenv.bat as Administraor
• Running conda install -c conda-forge selenium

The requested file doesn't exist in that path in my install either.

a missed dependency?  did you try --no pin

[SimonJackson]

Just tried from proenv.bat (run as administrator)

conda install -c conda-forge selenium --no-pin

Worked perfect.

Thanks Mr.P
