Install the LoadRunner Azure API Service

Vuser scripts can include Azure API functions, which enable access to Microsoft Azure Key Vault, a cloud service used for securely storing and accessing data. To run scripts containing these APIs, you need to install the LoadRunner Azure API Service on each load generator machine that runs the scripts. To replay the scripts in VuGen, install the service on the VuGen machine.
