I have created the first version of a detailed installation guide for HCL Sametime 12.0.x for Windows without using containers. This is a guide to basic installation and configuration so that you can easily and quickly start testing Sametime.
This is a companion discussion topic for the original entry at https://alichtenberg.cz/hcl-sametime-12-0-x-non-containerized-on-windows-step-by-step-installation-guide/
