SEPM 14.3 was a workhorse—the last version before UI overhaul and cloud-first features took over. If you’re reinstalling it in 2024+, just ensure your OS is supported (Windows Server 2016/2019 works best) and that you have the original license file (SLF). No license? SEPM won’t even let you past the first configuration wizard.
