Office 2013 Pro with Lync 2013 RTM is installed on a new Windows 10 desktop machine. As soon as you click a Lync or Skype for Business meeting invite URI, an error keeps appearing:
This operating system is not supported by this application.
[ OK ]
Despite having restarted the Lync application follow by reboot of the machine, the same error appears. It is getting late and you are not able to join the meeting. What can you do?
– append ?sl= to the meeting URI to join using the Lync/Skype Web App.
– first start one of the Office applications like Word to allow setup to complete the final installation steps.
