command line usage syntex error

Hi,
when I try to convert python code to c on windows with python file placed in same location where py2c.sh exists. I get an error running the following command

`py2c -o file Encoder.py --keep`
error
```
'py2c' is not recognized as an internal or external command,
operable program or batch file.
```
I get same error even if I run
`py2c.sh  -o file Encoder.py --keep`
