CIROS does not load .dlls whenever the corresponding prerequisite is not matched.
In this case CIROS does not find a valid Python installation installed on the system.

In most cases this happens during a re-install of CIROS or other Software that depends on Python where the global path is damaged or leads to an incompatible version of Python (too old or too recent).

In most cases this is solved by uninstalling all python versions including Launcher using the App-Center (Windows+X -> Apps and Features):


Afterwards reinstall Python from the CIROS Setup in order to install a compatible version. The corresponding version is available for install through Start.exe or by navigating to Addons\Python.
In the latter case, make sure to select adding the %Path% variable during installation process. This is done automatically during the CIROS Setup routine.
