It seems that HP has started to transfer the HIDClass driver to its devices again, but for various reasons, it cannot be installed on Windows 10. Various reports show that the HP HIDClass driver cannot be installed under Windows 10 with error 0x800703e3 and that the “try again” button does nothing.
From the current point of view, this problem arises not only on HP devices with the October 2018 update, but also on PCs with the April 2018 update (version 1803) or perhaps older. Only a subset of consumers seems to be affected, and everything seems to be related to a conflict with HP drivers.
If you have this problem, there is a workaround that seems to work for us and many other users. Note, however, that this is not an official solution. Use of this guide is at your own risk.
