12.1.2 MP1 Deployment Questions

Hi Everyone, 

I attached the new install packages and I am hosting the setup.exe via IIS. I was suprised that none of the clients upgraded. I figured at least a few of the PCs would have been rebooted. When I checked here is what I get for the deployment status:

Deployment status: The client has successfully downloaded and verified the upgrade package

Deployment message: Client has successfully downloaded and verfied the upgrade package, type full version 12.1.2100.2093 filesize 0.

Deployment target version: 12.1.2100.2093

Deployment running version: 12.1.2015.2015

Could anyone tell me what the means? Do the PCs need to be restarted?

Thanks, 

Mike
