How to reset old authorizations on Adobe Digital Editions?

Can't sign in to Adobe Digital Editions on PC.
The limit of the number of machines has been reached.
The old computers of those who quit are formatted and it is not possible to exit the Adobe authorization (Adobe Digital Editions on PC).
It is not possible to reset authorizations through Adobe tools. I found such an item when changing the password and it does not work for Adobe Digital Editions.
