The archives do appear to be downloaded and are present in the "temp" folder.
So the process to follow would be to reset to default in the Configurator, and then extract the contents of the archives to the main P3D directory?
The error message is very generic, just "there was an error with the program and it must shut down" sort of thing. I thought it might be related to microsoft .net framework, but apparently all of the relevant .net items are present and turned on by default in Windows 10. Also, I did check that all of the permissions for the P3D folder are set to Allow, and turned off my anti-virus.
I can certainly extract the archives manually if the process is as straight-forward as you describe.
