DJ, you continue to amaze. Thanks so much for your continued support.


Thanks, Dave! It's not all me, but I'll relay your gratitude. Also, a lot of the features are inspired by community feedback. So thank yourselves as well:D


So do both the free versions stop working after 1 hour? For example if I use the 1 free skill for an hour to try something new, save the go into the free read only version will that also stop after 1 hour?

There is no mention of Runtime having a time limit in the release notes. There is a time limit for Teams with free users. Runtime works forever. Runtime is so you can run a robot project forever, so you don't have to pay for a subscription for the robot's lifetime.

Teams will work with a subscription or a free user. If you're a free user, there are limitations. If you use Teams with a subscription account, there are no limitations.:)

Hi DJ, How do I download the ARC onto a second PC with it asking me to sign up and pay again? I'm sure its just a matter of pointing to the right place on the site. I Have latest ARC on a tablet, would like have it on  this new desktop also.

Thanks for the help:)


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



Thanks for the info. I have been able download and install now.
