I am in the process of a major upgrade from NPM 9.0 w/NTS 3.0 to NPM 9.5 SP4 with NTA 3.5 SP2. I did everything possible to prevent any issues with the install and did not have any problems/errors during the upgrade but get the following error when accessing the website.
"Orion License Error. License check failed"
I even got the message 'Your software license key is installed!' at the end of the installations of NPM and NTA. I have rebooted, checked IIS permissions, and even saved the registry keys top compare from the previous install. I assume I am not the first to experience this issue, so hopefully someone can provide some insight so I can get the system fully functional by Monday morning.
