11 years agoModelSim licensing problems after installing Opal Kelly license
I have a problem with my Quartus II installation, specifically that the ModelSim Altera starter edtion will not start, complaining about "Unable to checkout a license".
The thing is, I am using a development board from Opal Kelly (ZEM4310), which comes with some IP blocks that requires a license to be installed in Quartus II. Installing this license seems to break the licensing for ModelSim for some reason. I have tried removing the license file, but this does not help, I still have the same problem. I am not sure if there is a specific way a license should be removed, I have tried to remove the file in the Licensing setup dialog, and also actually deleting the file from my hard drive, but none of that helps. I am using Quartus II 14.1 on Windows 7. Ideas are welcome...
