Error loading v1.7 on Unity 2017.4

[bo3b]

Always possible I don't know what I'm doing, but I get an error when trying to load version 1.7 using Unity 2017.4.26f1.

When I create an empty new project, then do Assets->Import Package->CustomPackage, then choose the .package file from the download page, I get a missing .asmdef error.

Assembly has reference to non-existent assembly 'GUID:7547219be89abee4ba3cf7f48b516b7b' (Assets/uDesktopDuplication/Editor/uDD-Editor.asmdef)

If I do the same test using v1.6, I can import without any errors. And using the PrimaryMonitor prefab it runs without errors.

I'll use 1.6 for now, but thought it might be worth reporting.
