There is no workaround to find PYTHON27 registration information when installing PYWIN32

1. Check that the registry has information about other versions of Python

Method:

1) Enter regedit on the command line to open the registry

2) in HKEY_CURRENT_USER\Software find out if there is Python registration information, if present, check if it is python27 version, and whether it contains the following two nodes

Check again for the correct installation path. If you do not know how to check, you can right click on the Python node information to select Delete. If the Python registration information does not exist, there is no action.

2. Execute the Python script in the link below (python27 use normal, no need to modify any content)

3. After execution, check the registration form again. As follows

4. Install the Pywin32-220.win32-py2.7.exe again and the result is successfully installed

Another way: Just execute the following Python script

# Script to register Python 2.0 or later for use with Win32all
# and other extensions that require Python registry settings
