Windows client components require Python 3.9 environment

[ddlite92]

Currently, the Windows client components in cgru_tools require Python 3.9 environment to work correctly. This is necessary for proper functioning of tools like rqd and cuegui.

Steps to reproduce:

1. Attempt to run client components on Windows with a Python version other than 3.9.
2. Observe errors or failures related to environment compatibility.

Expected:

• Client components should either support newer Python versions or clearly document the requirement for Python 3.9.

Possible Solution:

• Update documentation to specify Python 3.9 requirement for Windows clients.
• Investigate compatibility with newer Python versions if possible.
