How do I resolve an "ERROR 202" when running grbgetkey?

The error message 

ERROR 202: Cannot get key code <licenseKey>

indicates our license server could not find your license key. This usually happens when the user is trying to install a WLS (Web License Service) License via grbgetkey.

To fix this issue, visit the Web License Manager and download your license file. You do not need to run grbgetkey for a WLS license, simply save the downloaded license file in one of the default locations as specified in the article Where do I place the Gurobi license file (gurobi.lic)?
