A family of Microsoft word processing software products for creating web, email, and print documents.
Hi Gopal,
Please open the registry for your PC and go to Computer\HKEY_CLASSES_ROOT.xlsx
See if the Default Value is set to Excel.Sheet.12
If it's not please manually change it to Excel.Sheet.12, Then try open the embed Excel workbook again.
Meanwhile, I would like to confirm with you if the issue is only occurring to this specific Word document or you won't be able to open any Embed Excel workbook.
If it's the second scenario, I would suggest using Online Repair to fix your corrupted Office component.
Regards,
Alex Chen
