Run testedApp for msi - wait till the msi has been completed

Hi, 

I have to install an msi; I'm trying to simply do it by using the testedApps, but I'm not finding a way to wait that the msi is finished the installation. 

The Run method doesn't wait that the tested app has finished the execution; in my case, the installation is finished when the msiexec process is terminated. How can I wait till the msi is finished?

This is my actual code:

let msiPath = "C:\\xxx\\";
let msiFileName = "xxx.msi";

function executeInstallationMsi()
{

    TestedApps.Installation.Path = msiPath;
    TestedApps.Installation.FileName = msiFileName;

    TestedApps.Installation.Run();
}

Thanks
