Error message: The Analysis Add-In is not registered correctly

Hi guys,

Myself and some of the Business users have been receiving the following message

I get this message when I try to view a file from the BO Platform (not via Excel). The users that get the message are unable to launch Analysis even if they select Close. They have to add the Add-In manually by ticking the Analysis name via the Add-Ins section.

The only thing that I am aware of changing it that we are rolling out Skype for Business across the company.

Has anyone else seen this error?

The users are on 1.4.7 but it happens on 2.1.2 and other versions.

I found note 1943590 which although it has a similar message, I don't think address the issue...

Thanks,

Stephen
