Hello Team,
I have standalone license key, I followed below steps for install and license activation.
Installed Studio->selected Enterprise ->check license acceptance->Continue->For me(downloaded in local PC->continue->selected Automation Developer-> Installed
it’s standalone license so selected more options-> standalone license option-> entered license key
If you entered the key only once and still get the error, most likely the license key has already reached its activation limit or it was previously activated on another machine. It can also happen if the Studio version doesn’t match the license type or if there were network/firewall issues during activation.
I’d suggest first checking whether the key was used on another PC earlier. If not, try deactivating it from the old machine (if available) and activate again. Otherwise, the best option is to raise a ticket with UiPath Support so they can reset the activation count for the license key.
