How To Renew License

Hello,
I am facing an issue with renew license. My Orchestrator is enterprise version - 21.1.16-release.17, it is using trail license and will be expired today. Now I got a new license key and would like to update, but I cannot find place to do that in Orchestrator. Then I tried in Activation portal, first entered form for version 2019.04 which is latest I could find, but no any confirmation received. Then I notice for later version the form is different, it requires an txt file. I dont know where to get it. so I need your assistance on this.
thanks.

Hello @kigroup.robot,

If you have an enterprise key, it’s better to contact the UiPath support to help you.

It will simply speed up the process.

I hope it helps.

Vasile.
