Today one of my customer had trouble using the Excel Workbook Designer in Dynamics AX (“7”). He got the following error when he tried opening the workbook in Excel:
The Error is No Applet Registration found
Turns out he had not installed Microsoft Dynamics Office Add-in which can be found here: https://store.office.com/microsoft-dynamics-office-add-in-WA104379629.aspx?assetid=WA104379629&sourcecorrid=a8afb77b-cfe0-4b70-baeb-f93fa38ad77b&searchapppos=0
Once this was install it worked great
