Hi Lanz60,

I'm using python 3.5.

I used pip install hwCounter from the command line without the interpreter too :

try running:
pip install -U setuptools
pip install -U wheel
and then try again install hwCounter if it's still happening

Also, make sure using proper pip (check python version):
pip -V

Sorry about not using the 'code' icons to insert code.

I've run 
pip install -U setuptools
pip install -U wheel
which upgraded both.

run pip -V
which showed
pip 18.1 from c:\users\sue\appdata\local\programs\python\python35-32\lib\site-packages\pip (python 3.5)
I'm still getting the same error.

Sue.

I just tried it, and it installed without a hitch:
(try_venv) larz60@.../Projects/TryStuff $ pip install hwCounter

This is a completely new installation of python, pip etc. Never installed on this laptop before. Though I did install python 2.7 first.

Can having a package like pySerial installed first have any impact on installing another package ?

How sensitive can python and installing packages be in relation to what gets installed first ?

Thanks,
