Any errors or messages? Either on screen or in the Windows event log?

The most obvious thing to try is to re-install FME, version 2019.2.0 is available here: https://www.safe.com/support/downloads/#past-versions

No, the splash screen pops up, then disappears

And in the Windows event log?

Have already repaired, uninstalled and re-installed.

If nothing works, consider contacting your FME reseller, or Safe support.
