Hi DJ, I want to load the latest ARC Pro on this brand new Win10 PC. So yeah, Its never had ARC on it before. Currently I use a Tablet for all my ARC, but now I want to have a second computer running ARC also. When I first tried to download, it would remind me that I am already subscribed but then still wanted a credit card. I understand you can have up to two sessions running? so I am assuming two pc's?
Hello Robo Happy,
Your subscription is applicable for two computers. You have one computer registered at the moment. When loading the software, you will be prompted to add the new computer to the registration. At no point will there be a credit card displayed. It looks like DJ sent a link to pressing the refresh subscription cache button to force the registration. As per the instructions, make sure there's an internet connection.
The process of adding a second computer to your subscription is the same as it was for the first computer. Load the software, log in as the same registered email account, and add the computer when prompted.
*Remember, you must be logged in to ARC with the same email address as the subscription
