FontLab Studio 5.1.4 and earlier cannot launch on High Sierra.

If Fontlab 5 is installed fresh after the High Sierra upgrade (or if the license file is removed), you will see this error message:

“Error initializing license system. Bad or missing or expired RLM license (-130)...”


The solution is to install Fontlab Studio 5.1.6 (a free update for 5.0/5.1.x)


People using axis-based (Multiple Master) type design in FontLab Studio 5 should not upgrade at this time.
