Unable to initialize the native configuration support external to the web worker process (HRESULT=0x80040154)

If Amphis Customer suddenly stops working and there is a pop-up message with an unhandled exception and a message 'Unable to initialize the native configuration support external to the web worker process (HRESULT=0x80040154)' this is caused by a Microsoft Update.

This is a Microsoft .Net Framework problem caused by a Microsoft Update. The update appears to disable the .Net framework version 3/3.5 You can reactivate this by going to Control Panel > Programs and Features. Select Turn Windows features on or off. Tick the .Net Framework 3/3.5 and click Ok and this should fix it.

(To get to Control Panel, click the bottom-left Windows Start button to open the Start Menu, type control panel in the search box and select Control Panel in the results)
