UiPath 2018.2.6 Error -4304

Hello everyone,

I installed UiPath 2018.2.6 Trial version but I get the -4304 error code during the activation (find below a screenshot).

How can I resolve this problem without whitelisting and/or, of course, deactivating the firewall (security reasons)?

Also make sure while activating you are connected to internet and you have not activated any version from this machine previously


Thanks for your reply,

I’m connected to internet and I’ve not activated any version from this machine.
In fact the problem is from the firewall but I can’t call the network administrator due to the company’s policy.

Is there a way to activate the free trial without deactivating or creating a permission rule in the firewall?
