Hello, Ian Marcuse.

I dare say that you have a problem activating Office on a Mac, not on a PC. Many users have been experiencing this error lately. Microsoft is aware of the problem and is looking for a solution.: https://support.microsoft.com/en-us/support/known-issues/unknown-error-0x0-license-not-found-error-microsoft365-macos
