Deactivation of Adobe Acrobat X

This is a problem that others appear to have experienced, but all the suggested fixes do not work.  The AI help facility is also unable to provide any positive assistance. 

I have previously purchased a stand alone version of Adobe Acrobat X.  I have always had it installed on two computers.  One of the computers had a Microsoft related issue and Windows 11 had to be reset.  The Adobe software was not deactivated before the computer reset was undertaken.  I have reinstalled Acrobat on the one computer and when I try to activate the licence, it tells me that it is already installed on two computers and I need to deactivate one of the computers.  Problem is that I cannot deactivate the software as the reinstalled version  does not allow this to happen and all the help solutions do not address this issue I am having.  I dont seem to to be able to connect Adobe directly anymore, so I am stymied as to how I am going to deactivate the software.  Hopefully someone will have a solution handy.
