@MaxyArthes let’s try to debug your issues step by step.
You deleted the license folder from your Studio machine? In order for it to initialize you have to open Studio first.
Second, what Orchestrator version do you have? In order to get the file easier, please use the activation portal for versions 19.4 and lower: Activation. There, in the Activate your license section, fill the license code, select your Orchestrator version and click Generate. This will give you the file with the correct data and you just have to try again in Orchestrator.
Let me know if this works for you.
