There is nothing in the information you've posted to help indicate why the installation may have failed. Are you using distributed repositories? Did you just check the package in? If you're using distributed repositories, did you perform a replication to push the content to the repositories?
If you are simply updating an existing VSE install, you don't need to use a Product Deployment task. Patches are pushed via Product Update tasks, or by right clicking and running Update Security from the Agent tray-icon, if enabled in your environment. If you are only pushing DAT/Content via product update tasks, you'd want to use the Update Security feature to perform an immediate update, or you will need to configure a scheduled Product Update task that will update patches and service packs.
Thanks Tomz2, Have been off until now and will try today.
We are using distributed repositories and the task respository sync runs hourly and is successful.
The packages where updated early last week but only started to be a problem on Thursday.
Have tried to deploy to devices with an agent but no AV and the task keeps failing.
Maybe the agents are not at the right level:
from 18.104.22.168 you have to bring them up first to 22.214.171.124 to install P7.
