Busylight UC for Cisco Jabber requires .Net 4. Not every Windows has this preinstalled. If you don’t have it installed, download .Net 4.6.1 here.

When you know you are running the correct version of .Net 4 but still having problems, please try a repair of .Net 4.x.

Still no luck: please contact us via the contact form or write us at [email protected].
