Starting VirtualBox machines fails with "Unable to load R3 module ... VBoxDD.DLL (VBoxDD)"

Starting any machine on VirtualBox 4.3.22 on Windows 7, is failing with the following errors:

Failed to open a session for the virtual machine Kivy.

Unable to load R3 module C:\Program Files\VirtualBox/VBoxDD.DLL (VBoxDD): GetLastError=1790 (VERR_UNRESOLVED_ERROR).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}


(BTW, I get the same errors on VirtualBox 4.3.20).


The relevant (last) log lines are:
