Hi denniz, you can set de VSE deployment task at the system tree top level so your clients execute this task every day.
When a computer launches this task they will first download the catalog.z file from epo server (a small file) and it will compare it with its own; if product is already installed then it won't download VSE again (nor install it again).
Thanks for the information. I did add the VSE deployment task to the node in my system tree (where i want this functionality). And schedule it on startup (or maybe will schedule it otherwise).
And this works exactly like i want it to!
