@sletz I'll need to check, but that installer is ancient. But yeah I'll be moving away from this installer solution going forward, that entire thing has been nothing but a complete failure from my part :)
At this point I would suggest you just build the development branch from HISE from scratch - the compiled binaries do not include the Faust toolkit so you would have to recompile it anyway to use Faust (which I assume you want to).
