Dorico activation

Hi! I had a major problem while tring to activate Dorico, I already used it months ago and it was activated succesfully but now i can’t boot the program and it said I had to do ‘‘mantainenance’’ of the ‘‘e-licenser’’, I did so and it seem that this can’t solve the problem because I get this message:

Which means that ‘‘the e-licenser software on this computer seems to be altered in an irreversible way, contact the productor’’
What can I do to use Dorico again?

Try starting the e-licenser as an Administrator. That usually helps. I agree that the error message is a bit unhelpful.

Please have a look at the following helpcenter article:

Your eLicenser Control Center needs to be updates as well.
