I installed Microsoft Office LTSC Professional Plus 2024 and now I get the error " Sign in Required We can’t upload or download your changes because your cached credentials have expired." I updated my Office 2024 activation code in the product code of my office documents. Document product says Product activated Microsoft Office LTSC Professional Plus 2024 when I go to File, Account, under Product information. But, I can not activate my product key on line.
How can I activate online?
