With UP8.3 SP1, we added Windows 8/8.1 Popup, Notify, and Pharos Station support; however, Pharos admin is not supported. If you are looking for full Windows 8/8.1 support, you need UP8.4, or UP9.0.
Thanks for the reply. I was hoping someone in the community had found a workaround. We won’t be able to upgrade for several months, but we have some people who have upgraded their workstations to Windows 8 already.
