Not Recognizing Gurobi License

Answered

Windows 11 - I saved my Gurobi license on to the default location c:/users/username. When I open cmd prompt and type “get key”, I get the following error: 

'grbgetkey' is not recognized as an internal or external command,
operable program or batch file. 

I previously had the file in lisence saved at the C:/ location, and when I used that location and opened the cmd prompt, the command “grbgetkey” did work, but the license key number did not work.

  Hi Christina,

  >I saved my Gurobi license on to the default location c:/users/username.
  If you already have your license file and saved on appropriate location, you don't need to run grbgetkey. The grbgetkey is just a tool for generating licenses.
   

  If you need to run `grbgetkey`, please refer to this article:
  How do I resolve the error "grbgetkey: command not found" or "'grbgetkey' is not recognized"?
