For LaunchBox version 12.14, it requires these dependencies:
Visual C++ 2015 Redistributable - https://www.microsoft.com/en-ca/download/details.aspx?id=48145
.Net Framework 4.8 - https://support.microsoft.com/en-us/topic/microsoft-net-framework-4-8-offline-installer-for-windows-9d23f658-3b97-68ab-d013-aa3c3e7495e0 (offline installer version)
My machine already has .Net Core 3.1 installed, so not sure if this is in addition or not. Attached is a screenshot of the LaunchBox install dependies.
