Your commands will look like this on Windows:
QualysCloudAgent.exe CustomerId={xxxxx-xxxx-xxxx-xxxx-xxxx} ActivationId={yyyy-yyyy-yyyy-yyyy-yyyy} WebServiceUri=https://qagpublic.qg2.apps.qualys.eu/CloudAgent/
on macOS:
sudo installer -pkg ./QualysCloudAgent.pkg -target /
THEN
sudo /Applications/QualysCloudAgent.app/Contents/MacOS/qualys-cloud-agent.sh ActivationId=xxxx-xxxx-xxxx-xxxx-xxx CustomerId=yyyy-yyyy-yyyy-yyyy-yyyy ServerUri=https://qagpublic.qg2.apps.qualys.eu/CloudAgent/
