Windows 10: Microsoft Office Activation Issues

Hi,I had to reformat my computer because it became corrupt. I saved my programs, personal files, but I didn't back up the registry where the key file would be stored?. I do still have the Office folder saved. I do have the key saved via purchase receipt though. I did a fresh install of Microsoft Office Professional Plus 2019, but I cannot use a key to activate it.It appears my Installation ID is invalid? When I try to activate using option 1 I want to activate the software over the internet, I get the following error: 0xc004c060. When I try to activate by telephone, it tells me my Install

:)

 

MS Office 2007 no more activated...

I contacted a support manager and the situation is:

1. With all my hardware modifications, I reached the limit number of activation (8).
2. Microsoft is no more capable to force a new activation.
3. They suggested me to uninstall and reinstall Office in order to redo an activation.

This last point is not good for me because of the time required, specially with the online updates.
May be, I have only to delete the product key into the registry but Microsoft is not able to confirm.
Do you have an idea before I try to crack it?

Download an iso with all updates and use your serial.
