LicenseNotAcquiredException in unity build

activation tool button is not enabled and shows “activated”… how to re-activate the license?

i think windows10 update caused it…? (pretty sure it was working last week)

*ok, probably caused by using different sensor… how to handle multiple sensors? (only 1 will be used, but another one is for backup in case the main one breaks…)

I had this same problem and solved it by reinstalling Nuitrack. Another sensor was used on the device, and to activate my new sensor I had to reinstall it. They really should make a re-activate button though.


easy way seems to be removing/renaming the license file (license.json) in nuitrack/data/ folder,
then can run activator tool again.
