'This product is already installed on another device' message issue

Is it possible if this can be escalated? I have two friends who experienced the same issue. My theory, could be related to an update.

Things were done so far:

• Ran the SaraTool to uninstall
• Remove Office via the registry
• Removed the Microsoft Account within Windows (Settings > Account)
• Tried the Offline installer
• After re-installing, still getting the same error 'This product is already installed on another device.
• Even from the MSA account, it does not let the user use the key since the key is unviewable via the "services and subscription" tab and take note, Office license was purchased separately and it did not come preloaded

Hope anyone can answer this.

Thanks,

Rich

Hi Rich,

Contacting technical support team, will solve your problem.

Which version of Office is this? Phone activation may be required for older versions; see https://support.microsoft.com/en-us/office/-telephone-activation-is-no-longer-supported-for-your-product-error-when-activating-office-9b016cd2-0811-4cb3-b896-5a6a13177713.

Hi,

I am facing the exact same issue you had. I tried contacting Microsoft support via (https://widget.rave.office.net/)  but they asked me to contact the HP store where I got my laptop instead.

So I did. and they asked me to contact Microsoft! I've just been going in circles.

Was your issue fixed by remote screen sharing on this website https://widget.rave.office.net/ ?

That sounds madly frustrating. Mine was fixed by remote screen sharing. Through this: https://support.microsoft.com/contactus 

Good luck!!
