ImportError: DLL load failed while importing _rtmidi: The specified module could not be found.

Discord user nobodybelievesyou has reported this error occurring on several Windows machines with a freshly-installed development environment.

A similar issue was reported here: https://github.com/SpotlightKid/python-rtmidi/issues/91 Which suggested that installing vc_redist.x86.exe was required, however this has not remediated the issue with DBT. The linked python-rtmidi issue 91 also pertains to an ARM system, whereas this error is occuring on x64 Windows systems.
