Maximum numbers of Macs for elements

Translation:

“Is there a maximum number of Macs on which Elements can be installed? I have it running on 2, but it doesn’t work on a third one. I receive a message saying that either my email address or the code is incorrect, but I am 100% sure they are both correct.”

I thought it was 2

Yes, the limit is 2 “activated” Macs at a time. You can deactivate Macs from the registration window.
