License support for older versions of quartus prime.


We had to move our server, which hosted an older version of quartus prime. We regenerated our license (with much trouble, requiring much support from intel licensing support after intel bought altera), and finally got it running.


However, our alterad.exe crashes quite often. We've recieved a new file that fixed the issue for a while, and now it's crashing again.


I contacted, and they generated yet another license file. This file won't even load, and causes lmtools.exe to crash when trying to read the server statsus.


OS is windows server 2016, with the latest updates installed.


How do I generate a good license file that will work with our FlexLM server? Or how do I recieve the new FlexLM server files to run this license?


This is getting reall expensive not being able to develop our FPGA code right now.
