Can't install pymesh

[FBU]

Hi everybody,
I'm trying to install the library Pymesh (https://pymesh.readthedocs.io/en/latest/...ing-pymesh).
Everything went OK until the building step.

The command I tried :

.\Git\PyMesh>python setup.py build

The answer I get :

"running build
error: [WinError 193] %1 n’est pas une application Win32 valide" (in English : %1 is not an available Win32 application)

I tried to reinstall setuptools, but it was already correctly installed :
"pip install setuptools
Requirement already satisfied: setuptools in c:\users\francois.boureau.1\appdata\local\programs\python\python37-32\lib\site-packages (40.8.0)"

How can I solve the problem ?

Here is my path variable :

PATH=C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\Program Files\Common Files\Microsoft Shared\Microsoft Online Services;C:\Program Files (x86)\Common Files\Microsoft Shared\Microsoft Online Services;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\WINDOWS\System32\OpenSSH\;C:\Program Files\Microsoft SQL Server\120\Tools\Binn\;C:\Program Files\Common Files\Autodesk Shared\;C:\Program Files\Common Files\Graitec\;C:\Program Files (x86)\Common Files\Graitec\;C:\Users\francois.boureau.1\AppData\Local\Programs\Python\Python37-32;C:\Users\francois.boureau.1\AppData\Local\Programs\Python\Python37-32\Scripts;C:\Users\root\AppData\Local\Microsoft\WindowsApps

Thank you for your help !
