Exchange Server Cumulative Update Gets Stuck at Languages Step
The Exchange Server cumulative update installations can get stuck at Languages step.
The solution is very simple if you have System Center Endpoint protection on your exchange servers.
Just disable real time protection if you’re allowed to, if not you can allow “disabling” from SCCM configuration. Didn’t help?, just uninstall it.
Exchange CU installation will continue then you can install SCEP after the CU Upgrade.
Hope it helps
