I'm working on an application that uses the matlab engine API for python. The app works fine, without any issue, therefore I wanted to pack it into a single exe.
At first I had an issue given by mlarray, that I solved by compiling with:
pyinstaller --additional-hook-dir=hooks --onefile main.py
Now on my own computer the .exe file works fine, but as soon as I try to run it on a different machine (with Matlab installed), it gives me the following error:

It seems that it can't find the module "matlabengineforpython3_8", which in theory is in the engine folder in the matlab installation path. Then it's looking for a file in the wrong place, because the machine doesn't have an F: disk, but my computer does.
