One of our users was on Excel 2013 and IBP was working fine. She was upgraded to Excel 365 and now gets the error "SAP IBP Add-In Launcher has stopped working" when opening Excel. This is followed, in the same dialog box, by two "Class Not Registered" messages. We do have other users using Excel 365 and IBP without any issues. I believe this is an issue of IBP being loaded when the upgrade was done.
I checked her com add-ins and see that the "SAP IBP- Technical migration add-in (required)" add-in is no longer listed as a choice to be made active. I do not know if this is what is causing the initial error message. But, I also am not sure how to add this as the path (when looking at my configuration) is not just a file name (file///c:\program files\sap\excel addin\FPMXLClient.Connect.vsto|vstolocal).
I had the IBP software re-installed, but the problem still exists and the com add-in is still not in the list to add.
Any suggestions on how to resolve this issue would be greatly appreciated.
