[BlenderBIM] installation problem

Nigel

I have been struggling to get Blender BIM to install. When i 'tick the box' to enable I get the following Traceback... I know it's me :) Some insight into why it's me will be really appreciated.
Traceback (most recent call last):
File "C:\Users\nigel\AppData\Roaming\Blender Foundation\Blender\3.4\scripts\modules\requests\compat.py", line 11, in
import chardet
ModuleNotFoundError: No module named 'chardet'

During handling of the above exception, another exception occurred:

ModuleNotFoundError: No module named 'chardet'

Seems to be this module after googling:
https://pypi.org/project/chardet/
That is odd because BlenderBIM works for me without this module, I also don't have it installed.
Maybe some other add-on is causing it?
Atleast what you could try is trying to install the chardet add-on from Blender and see if the message dissappears

import sys
import subprocess
py_exec = str(sys.executable)

# ensure pip is installed
#subprocess.call([py_exec, "-m", "pip uninstall pip", "--user" ])
#subprocess.call([py_exec, "-m", "ensurepip", "--user" ])
#subprocess.call([py_exec, "-m", "pip install -U pip", "--user" ])
# update pip (not mandatory but highly recommended)
#subprocess.call([py_exec, "-m", "pip", "install", "--upgrade", "pip" ])

# install packages
subprocess.call([py_exec,"-m", "pip", "install", f"--target={py_exec[:-14]}" + "lib", "chardet"])

Or try disabling all other add-ons and see if the message dissapears

@Coen thank you for your help, alas to no avail. It is doing my head in, I have disabled all Addons, reinstalled Blender. Now lost for clues :(

Try installing a latest unstable release?

@Coen OMG I'm such a dummy, I needed to run Blender as an administrator and your code worked, BlenderBIM enabled successfully. Thank you. I'll write that on a post note and stick on my monitor :)
