### 🐞 Description of the bug

create virtual environment does not work on machine where there is no global python is installed, and even if it is installed most probably it wont work with the `Ansys Python` which is in the installation directory.

I have dug little bit into the code and seems like following command does not work

```shell
start /w /min cmd /K "set PATH=C:\Program Files\ANSYS Inc\v242\commonfiles\CPython\3_10\winx64\Release\python && python -m venv C:\Users\mkanchan\.ansys_python_venvs\test_venv && exit
```

this command when run in the console (cmd.exe), does not work and shows that `python` is not a command or executable

**PS : the successful creation should check if the venv is actually created by checking the executables and `activate` files**

**PS2: in this template remove the `I am using a Python virtual environment`, this is not a standard for this repo**

### 📝 Steps to reproduce

- make sure you do not have global python installed on your machine
- fire up Ansys Python Manager
- select one of the ansys installation python
- create venv
- it says it sucessfully created but in reality the folder is empty
