From the screenshot it can be seen that Revit can not find the add-in in the mentioned folder.
So check if that folder exists at all and also look if the Insight360 is located somewhere else.
Also looking at the insight360 website I see that the prerequisite is Revit 2016 R2. So make sure that you have all the updated upto at least R2.

Please mention Revit version, especially when uploading Revit files.
