I was attmepting to follow the documented directions for deregistering a Windows 10 computer so that I could install Epubor Ultimate on a new Windows 11 computer. I do not have a tab for deregistration in the tools menu on Epubor Ultimate on my old Win 10 computer. I am running version v3.0.16.599. Do I need to contact support to have them derester for me or am I missing something?
