Hi Peter,
with v1603 the widescreen GUI works, with v1703 not.
You can download and install v1703, when you go to settings/update and security and signing on for the creators update. Click on the blue writing.
After confirming the privacy policy, you will receive the creators update.
As I said, Ahnenerbe's widescreen and MaGui work with CCoM under v1703. LSH3 V15 is based on CCoM.
