If you have full Finale, you are allowed 2 installations, so if you only installed on the one computer, you should be OK. You might want to contact Make Music and explain what happened and ask that they free up the first, non-working computer so you have that additional installation available "just in case".

I have contacted them, but their support is only by e-mail.  The instructions are not possible.  They describe a screen that does not exist. My follow up question was not answered.

Hi David,

I see you have a support ticket open currently about the issue (#92357). One of my colleagues just replied a short time ago to clarify some details so we can help you clear the authorization from the dead computer. Please check your email inbox or the "My Requests" tab at the top of this Help Center page for his latest reply.

You have two web sites.  The support tab on the one I was using needs to be updated.  I was using https://www.finalemusic.com/.

I did reach the screen I needed.  The proper computer listed has been deleted.

Thank you

If you log into your MakeMusic account, you can click on Manage Authorizations to delete old computers. 

Only if you are on the right web site.  This one does not work:  https://www.finalemusic.com/.

That's the one I always use, and it just worked for me. I went there and clicked the My Account link, and everything came up just fine.

Your user account should be available from either url. Click on My Account and log in. The link is small but it's there.

Worked for me just now.

The mystery is solved.  I was going through "Support."  I did not know that I had an account.  I do not remember setting one up.  I started using Finale in 1999 and have always used "Support."  There have been a lot of changes since then; now, there is something new to me.

Thanks for the follow up. That's good to know. Looks like problem solved.

So the real issue is that you were unable to transfer license authorizations through Support on the old site (or something like that). In the absence of organized threads, I'm writing this description to make it easier to find this in a site or Google search.

It will affect someone else down the line. I think we can count on that.
