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,

  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"?
