I forgot to choose this option "python disable path length limit" during the installation and close the installation window. How can I activate this option now?

Apparently this option in the Python installer changes a Windows 10 setting to allow longer file paths.
- Run Regedit
- navigate to
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
(you can past this into the address bar in Regedit) - set
LongPathsEnabled
to 1
For more info refer to Python installer for Windows: disable path length limit option not available and Python Setup Disabling Path Length Limit Pros and Cons?
