Pyinstaller installed succesfully but not working

Question

When I try to write pyinstaller 'filename' it gives me an error

pyinstaller 'filename'                                                                  
'pyinstaller' is not recognized as an internal or external command,                                                     
operable program or batch file.     

Whatever I try

python -m pyinstaller 'filename'
`No module named pyinstaller`

Please tell solution for it (also, the pyinstaller is successfully installed)
