Background

CKAN Version:
1.25.0

KSP Version:
1.4.3.2152

Operating System:
Win 10

Have you made any manual changes to your GameData folder (i.e., not via CKAN)?
No

Problem

What steps did you take in CKAN?
I double clicked the .exe (which is placed on the same drive as KSP)

What did you expect to happen?
Launching ckan

What happened instead?
I got an error that read:

Unhandled exception:
