Hi,

I got the following output when i run my program:

No HostID specified in license file

I added the system variables for the license file. But it remains the same.

Please help to suggest!

  Hi,

  Apparently, your license file is not set up for your machine. You may need to run grbgetkey to do that. Please also refer to our documentation and the Quick Start Guide.

  Cheers,
  Matthias
