License not working

[ptc-2486071]

License not working after reintalling computer`s operating system from a backup. I am trying to load the license file and it is not working("Invalid Host", "the host ID doesn't match the hostID specified in the license file"). Also online I cannot make the license work(i get: The remote server returned an error(403)Forbidden).

Hi @ptc-2486071,

Your machine's Host Id may got changed. Contact PTC License Management or try generating license file using link - https://support.ptc.com/appserver/cs/lm/index.jsp.
