Win10 - Windows Update error, build 10056

[ewan]

hi - I'm on Win10 build 10056 and the DisplayLink via my Targus USB replicator was working OK, but as of (I think) Weds 17th April, a Windows Update appeared for the DL driver (I was on Alpha 8).

The WU fails to install, with DisplayLink Corp. driver update for DisplayLink Display Adapter (4306) - Error 0x800f0203. I've tried unplugging, removing the existing driver (deleting files), removing the DisplayLink s/w, rebooting, installing Alpha 9 of the official driver... but the WU is still being offered and failing to install.

After all of this, the DL driver is no longer working either - the DisplayLinkManager service terminates unexpectedly and every 5 minutes or so, the machine goes through a device discovery process, both screens flicker with the desktop showing as expected, and about 10 secs later it fails and screen 2 goes blank.

Any help appreciated
thanks
Ewan
