Under Assets and Compliance go to Device Collections → Faculty-Staff → Faculty Staff Software Deployment and look for the collection named for the software you are deploying (not all software will be deployed to a collection with the exact name of the software).
Start the SCCM Console using appropriate credentials.
Ensure the computer appears in the SCCM Software Deployment collection.
After moving the computer into the correct OU, collection membership may need to be updated (this will happen automatically usually within 1 day or less, or can be performed manually).
Move the computer to the correct OU for the department or lab it belongs to (or wait for ADSorter to run).
If the computer has not been moved to the correct OU, software may not be available in Software Center.
Some software deployments are based on AD OU.
Ensure the computer is in the correct Organizational Unit in AD.
Press F5 with Software Center in focus to update the list of available software.
If Software Center is left open, it may not refresh automatically when new software becomes available.
Refresh Software Center with the F5 key.
You can sign out other users by launching Task Manager and going to the Users tab.
Task sequences will never appear if another user is already signed into the computer.
Ensure you are the only user signed into the computer.
These suggestions also work for task sequence deployments.
