I feel like a big old doofus, I put it in the softrak/system folder on my local machine instead of the server. It works great once you get it in the right place!

Well - that's nice to hear!

The Softrak SetScreen utility worked great on a Surface 4. The Windows 10 Anniversary Update reset the "PreferExternalManifest" registry setting and the scaling went back out of whack but it was quick work to replace the registry entry.

The Graph-On client that Adagio Cloud uses exhibits similar problems with scaling on high res displays. Is a similar gg-client.exe.manifest fix possible? I've tried on my own and it starts complaining about missing VC DLLs and that's as far as I'm going down that path.
