Unable to use Making History in 6.0

[Lar-E]

I downloaded and installed the latest ksp (6.0, 64bit), and the corresponding Making History this morning on my Windows machine. Upon installation, Making History gives me an error message: "You are running a version of Kerbal Space Program that is not compatible with the Making History Expansion. Please go to KSP store and download the 1.6.0 version or above."

I have run KSP, and can confirm that I am running version 1.6.0.2395

I also re-downloaded and reinstalled both files this afternoon. Same result.

What gives?

I have only seen this error when I got my install folders mixed up.

The Making History and KSP version numbers match now, 1.6.0 for KSP 1.6.0 (different to how it worked a few months ago).

KSP 1.6.0 has a buildID64.txt with "build id = 02395  2018.12.20" and Making History 1.6.0 has an uninstall.dat with "KSP-Making_History_Expansion-en-us-v1.6.0"
