A Software Delivery job is pushed to a client computer, using a Managed Software Delivery Policy, Quick Delivery Task, or Package Delivery Task. The execution starts properly, but then fails to complete, and is terminated after six hours.
The default setting for software installation is to time out/terminate after 6 hours, or 300 minutes.
It is recommended to keep the terminate time enabled, although the time can be increased or decreased depending on the application.

If a software deployment fails to complete within that time, a message was likely displayed and required interaction, and was not clicked. Check the following:
Test the installation with these settings enabled. If a popup appears, check the installation command line to determine if a silent switch or other setting is missing. Various applications have different ways to install software silently or unattended. This could be as simple as adding a /s switch on the command line, or /qn for an MSI installation. Check with the software vendor to see recommended ways to install software silently.
