Hello, At the moment we are using sccm 2012 for deploying msi and app-v in our citrix vdi environment. In the vdi is an sccm client installed and also on the local machine. Is it possible to disable installing software (Applications and Packages) on the local machine and use it only for updating the system? Now the same software is trying to install local and in the vdi environment. Within the Applications menu i've set up some requirements to deploy only on pc's inside an OU. This works for the app-v packages.. But in the menu for Packages there's no requirements option to only install on pc's inside an OU. So these software appears on local client. Thanks for an answer
