Hi - I have Docker installed and running (e.g. can run the hello world docker image), but when I try doing a local lean backtest still get the Please make sure Docker is installed and running issue.
Here's the output when running lean cli in verbose.
Thanks!

Hi Gui
It seems pywin32 is not installed, the following should fix it:
Also, please make sure you've updated to the most updated LEAN CLI version by pip install --upgrade lean and the python is not installed from the windows app store. If the above solution doesn't work, please uninstall and reinstall from scratch (doc).
Best
