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
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.

Okay great to know DJ!
You bet, anytime!
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
