Hi Abhi_MSoffice,
Thank you for posting in Microsoft Community.
I do understand and appreciate your posting. Please check if the add-ins were installed and check on the Excel Add-ins menu.
To check it. Please follow this steps:
- Click the Windows Start menu > type RUN > Open the Run app > type on the dialog box "excel.exe /safe" > click Ok.
- Once the Excel run on Safe mode which you will notice it since the ribbon bar background will be on white. Click File tab > Options > Click Add-ins > Click the dropdown menu and select Com Add-ins and then click GO > Mark as check the Add-ins you are trying to use and then click OK.
- Close the Excel in Safe mode and reopen the Excel apps the normal way you open it and check if the Add-ins are now.
