PS CS5 reinstall on a win10 This serial number is already in use.

Question

After reinstalling Win10 on my PC I noticed that my DVD with PS doesn't work any more, so I tried to register the serial number on the Adobe page to maybe find a downloadable version of CS5 extended, that is when I got the error message:

This serial number is already in use

I used to have this software on the same PC before the reinstall... What should I do next?

there's now only one way to do that, now. in the past, there were several ways including asking adobe support to reset your activation count, but that no longer works.

use the computers (if they exist, still run AND can communicate with adobe's deactivation server) with the activations and open an app > click help > deactivate. if you've already uninstalled the app before deactivating, but still have an operable computer, you can reinstall on that computer and then deactivate.

the big catch is can those computers communicate the deactivation with adobe's servers.
