The Python installation is a part of the original Python installation plus CRT Runtime.
- Python installation is required to run tribe python scripts(or custom in most cases).
- CRT runtime(DLLs) is mandatory for some special cases, like not updated Windows, older Windows, Windows without Service Pack, whatever.
- Python installation isn’t broken, of course, it works pretty well
You should not set PYTHONHOME normally. This is just dangerous and usually useless. There are still few exceptions, for example, embedded systems. Or very special systems.
Yes, you are right, if you really need a PYTHONHOME, please, create a corresponding ticket and I will find a solution. I know about this problem.
