So I was starting to get into streaming so I wanted to download Streamlabs however whenever I tried to download it it would always go about halfway and then say:
Setup was not completed successfully.
I don’t know how to fix this because whenever I delete and then reinstall the downloader the same thing comes up.

Can you navigate to your control panel, and uninstall Streamlabs OBS from there specifically.
Then download the new installer > run as admin.
do this it worked for me
