Client stuck under Quarantine [Solved]

We've got a client that we previously quarantined via EMS that will now not come out of quarantine after right-clicking it in EMS and selecting 'Unquarantine'. We've tried to exclude/re-manage and finally mark as uninstalled. Now EMS is attempting to reinstall (per policy) but nothing is happening on the client's end.

Solved: Ran FCRemove in safe mode, rebooted and the client reinstalled from policy normally.
