I am trying to install the MATLAB engine for Python on my computer and when I write
python setup.py install
I get the following error:
error: could not create 'build': Access is denied
The same error also occurs when I try 'builddir'
I also have administrator access on my computer so I am confused as to why I am being denied.
Any help would be greatly appreciated!

The same thing happened to me. Solution: Right click on Command Prompt and Run as Administrator. Problem solved!

On Windows, you may need to run the prompt as administrator in order to write to protected folders even if you have administrator access.
Try to search "cmd" on Start and right click on it, select "Run as administrator" to see how it works.

Dear all,
If this problem is still exist.
Please, just dubble check that the full access is enbale for the following folders:
MATLAB:
C:\Program Files\MATLAB\R2021b\extern\engines\python
PYTHON
C:\Program Files\Python39\Lib\site-packages\
Then, using this command to install the API engine for Python by windows shell (cmd).
python setup.py install
Hope it would be useful :)

A better solution, especially if you don't have Admin access to the machine, is to specify the build directory:
python setup.py build -b C:\Temp install

You can use the following:
Please change <<username>> to your username on the machine
python setup.py build --build-base="C:\Users\<<USERNAME>>\Documents\MATLAB\pythonengine-build" install

I'm facing the same error when I tried to install in matlab command window. when installing in cmd run as administrator is fine. does anyone know how to fix that error?
cmd: Installed c:\users\appdata\local\programs\python\python37\lib\site-packages\matlabengineforpython-r2020a-py3.7.egg
Processing dependencies for matlabengineforpython===R2020a
Finished processing dependencies for matlabengineforpython===R2020a
in matlab: error: [WinError 5] Access is denied: 'dist\\matlabengineforpython.egg-info'
if it's installed by cmd, why am I getting "ModuleNotFoundError: No module named 'matlab'" in jupyter?
