MATLAB: How to chose the correct version of python when trying to install the Matlab Engine API

MATLABmatlab engine apipythonpython installpython version

I'm trying to install the Matlab Engine API for Windows. I have both Python 3.7 and 3.8, with 3.8 being my default version. When I try the command
python setup.py install
it gives me an error saying my version is 3.8, which isn't accepted. I then triend the command
python setup.py -3.7 install
but it gives the same error message. Any help would be appreciated.

As of R2020a, Python 3.8 is not supported yet. Your "python" command is an alias of Python 3.8, so you need to specify the full path of Python 3.7.
For example, if Python 3.7 is installed in C:\Program Files\Python 3.7,
"C:\Program Files\Python 3.7\python.exe" setup.py install
Double quotation is necessary if the installation folder contains spaces (like Program Files).
Please keep in mind that 64 bit versions of Python are necessary to user MATLAB Engine API of R2020a.
