TechSmith Relay (Self-Hosted): Encountering an Error 5100 when installing .net 4.5.2 Prerequisite

While installing the Relay 4.4.x update an error 5100 may occur, indicating the installer could not appropriately install or update .net 4.5.2.

This is often caused by a pending reboot required by another Windows Update.   To resolve, simply reboot the server and restart the Relay installation process.
