1. First install pyenv with the following command:
{color_text(('Invoke-WebRequest -UseBasicParsing -Uri "https://raw.githubusercontent.com/pyenv-win/pyenv-win/master/pyenv-win/install-pyenv-win.ps1" -OutFile "./install-pyenv-win.ps1"; &"./install-pyenv-win.ps1"'),self.theme_cls.tertiaryColor)}
2. run the following command to check if successsful:
{color_text(('pyenv --version '),self.theme_cls.tertiaryColor)}
3.  run the following command to install python 3.10
{color_text(('pyenv install 3.10'),self.theme_cls.tertiaryColor)}
4. To confirm successful install of python 3.10 run the following command and check if 3.10 is listed:
{color_text(('pyenv -l'),self.theme_cls.tertiaryColor)}
5. Next run: 
{color_text(('pyenv local 3.10'),self.theme_cls.tertiaryColor)} (if in anixstream directory to set python 3.10 as local interpreter)
or run:
{color_text(('pyenv global 3.10'),self.theme_cls.tertiaryColor)} (if in another directory to set python version 3.10 as global interpreter) 
6. Check if success by running and checking if output is 3.10: 
{color_text(('python --version'),self.theme_cls.tertiaryColor)}
7. Run:
{color_text(('python -m pip install animdl'),self.theme_cls.tertiaryColor)}
8. Check if success by running:
{color_text(('python -m animdl'),self.theme_cls.tertiaryColor)} 
{color_text(('Note:'),self.theme_cls.secondaryColor)}
All this instructions should be done from the folder you choose to install
aniXstream but incase you have never installed python should work any where
