Context information (for bug reports)
- Output of
pyinstaller --version:6.1.0 - Version of Python: 3.12.0
- Platform: Windows
- How you installed Python:
scoop install python - Did you also try this on another platform? No,
scoopis Windows-only. - try the latest development version, using the following command: same result.
libffi-8.dll seems to be packaged in the wrong location inside the MEI, see https://github.com/orgs/pyinstaller/discussions/7431#discussioncomment-7335377.

Thanks for the initial analysis! This sounds like a DLL parent path preservation bug (which seems to affect either
scoop-installed python, or perhaps python without virtual environment in general). I'll look into it.bersbersbers commentedon Oct 20, 2023
Beautiful, thank you! It's not the only place where
scoops symlinks/junctions create problems, but I'm happy you choose to support it.
