15 years agoI just experienced a similar problem; Quartus had completed a couple of builds successfully, then, without shutting it down, it decided it couldn't find a licence (licence in use).
Re-start of Quartus didn't fix. Licence is permanent, so not expired. No-one else is using it. Couldn't see any obvious Quartus processes in Task Manager. Re-boot of PC fixed the problem, so I suspect Quartus got a little 'confused' about the state of its licence.
