welenbaul93 0 Posted December 9, 2020 Share Posted December 9, 2020 So I have a license for EIS, but I can't activate it. It always says: Failed to connect to activation servers. ECP20003. (I'm running win10 64bit). I was able to activate the same license on laptop with win 8.1. Link to comment Share on other sites More sharing options...
