As far as I know Fusion doesn't support Python 3.9.

To run Prism in Fusion you need to install Python 2.7

I think Python Python 3.6.8 is also supported in F9

Thank you. Is a reinstall of Prism needed to get it working? System reboot?

True, but the PySide2 libraries, which are shipped with Prism are for Python 3.7 only. That means you need to install PySide2 yourself either for Python 2.7 or 3.6. For example by executing this in the windows powershell:

pip install PySide2

No, you don't need to reinstall Prism and a system restart is also not possible. Just make sure you installed Python and PySide2.

Thank you. The power shell gives me this:

PS C:\Users\mr> pip install PySide2

pip is a package manager for python which allows you to easily download other python packages.

Looks like pip isn't set up yet on your computer, but you can do that easily by following this guide:

thank you. This will give me:

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

pip install PySide2 will give me the same error as above.

Isn't Python 3.7 (inc PySide 2) included in the Prism installation? Isn't that the python Prism is running on or does it use the system installed python?
