It gives No eService found for this registration key. And when I tried to connect eService it also give me error, Like There was a problem loading the eService setup window.
Any solution on how can I resolve this error?
Is this a new database with a valid registration key? When you navigate to Setup > Advanced Setup> API, does the new window pop up or do you get an error message straight away. In either case, what is the exact error message displayed?
Another thing to note is that a web call is made when this window opens. Is the machine you are using Open Dental on connected to a reliable internet connection?
