If you are seeing a 'Xenocode Postbuild 2008 error - Unable to load a required virtual machine component' we have a few options to try.
Xenocode has not been used in Schedule It for many years so if you can update your version this will prevent this being an issue with any future updates to Windows.
An update from Microsoft KB3045999 is also known to cause this error on some computers. Removing this update allows it to run until it is applied again automatically in the future.
