Upgrade to Cubase 15 Pro plus Wavelab 13 - wavelab won't start on ONE computer

I upgraded from Cubase 12 Pro to Cubase 15 Pro on 3 computers that also contained Wavelab Elements 11.2.

Wavelab 13 was also installed when Pro 15 was. And Authorized “automatically” when Cubase was.

On TWO of the computers I can use Cubase 15 and both Wavelab programs.

On the third I just installed, Wavelab 11.2 works along with Cubase 15 Pro but Wavelab 13 (Startup) says NO LICENSE and won’t start.

What can I do?
