Mix doesn't prompt anything in CMD

Hi everybody

I just started learning Elixir. I am using windows 10. My elixir and mix batch files are in the same directory as they should be. Those directories are in both system and user variable paths. --version check for Elixir is only working when I start CMD with admin rights and while I am in this directory C:\WINDOWS\system32>. But version check for mix is not prompting anything in system32 directory. If I am in a different directory(doesn’t matter the admin rights) both version checks doesn’t prompt anything.

Could you help me please?
