Hello,
Welcome to the Microsoft 365 and Office Community.
Good afternoon, @Govind Pataliya . Support for Office 2010 ended on October 13, 2020. Since then, the product has not received security updates, fixes, official technical support, or Windows Update-distributed updates to address issues specific to Office 2010.
Therefore, if you are trying to update or obtain a package directly through the old Office 2010 mechanisms, certain services or servers may no longer be available for this version.
You can try installing it manually via the Microsoft Update Catalog or the official Microsoft page for the package using the link below:
