Select a specific python version for CPLEX installation (Windows 10)

I'd like to install IBM ILOG CPLEX Optimization Studio 12.9.0 (by double-clicking on its ".exe" executable file) on my PC which runs Windows 10.

In this link there's a brief installation guide, which says:

"The modules associated with the CPLEX Python API reside in the directory yourCPLEXhome/python/VERSION/PLATFORM, (or in the folder yourCPLEXhome\python\VERSION\PLATFORM) where:

  • yourCPLEXhome: specifies the location where CPLEX is installed as part of IBM ILOG CPLEX Optimization Studio;
  • VERSION: designates a version of Python compatible with CPLEX;
  • PLATFORM: stands for your combination of operating system and compiler."

On my PC reside two different Python versions: 3.5.9 and 3.7.3, respectively.

I want that CPLEX will work only with Python 3.5.9; in other words, I want that the field VERSION in yourCPLEXhome/python/VERSION/PLATFORM will be 3.5.9, and not 3.7.3.

So, how could I choose a specific Python version to use with CPLEX?

The installer will always install both versions. Which one is actually use depends on which of the two you activate by running setup.py or to which you point PYTHONPATH.
