External node calling a python script: access denied

Thanks, reinstalling into a new folder as mentioned in the guide indeed solved the issue

I had similar issues with Python when I first started using it. Strange permissions issues. Attached is a reference I put together for installation that has worked well for me. Others may disagree with some settings, but this is what has worked great for me developing Python apps for FreeFlow Core for over the last 8 months or so. I found that when installed into 'Program Files' etc that the modules would often fail to update because of location or permissions. If this doesnt work for you then you might want to share your .bat file and Python script for testing (I would be happy to help validate for you). If you share your files you will need to .zip them.

Tried to set up an External node calling a python script through a bat file, following an example posted on this forum, however all I am getting is "Access is denied." in stderr.log - how to fix this?

System is Windows 10 Pro 21H1

Python v. 3.9.7

Calling python from regualar command prompt works just fine.

Calling the bat file from command prompt which in turn calls the python script also works fine, so seems like it only does not work when FF Core calls it.
