When upgrading maps for office from a version older than 3 to version 4.1 the old maps crash when trying to update them to the new version with the migration add-in as is suggested online. What could be the possible reasons for it crashing?
Is it crashing when you are opening the worksheets containing the older maps?
Jep, when I open Excel documents containing the old Maps for Office it crash and locks other new Excel documents.
I hope you have checked the Supported environments—ArcGIS Maps for Office | ArcGIS .
