Change Release Notes
loading and saving project is much faster now
Improved speed and memory usage of loading and saving files, both locally and on the cloud
Significant cloud saving performance improvements by compressing the upload
Large projects (~ 100mb) do not produce "out of system memory"
*Note: I've been able to test unicode text for foreign languages saving/loading. And while my tests do work, please verify your project load and saves correctly from the cloud and local if you have foreign language/characters.

Upgrade to ARC Pro
ARC Pro will give you immediate updates and new features needed to unleash your robot's potential!

Here's a video on how to download ARC Early Access. This applies for either first time or upgrading.
RoboHappy, by any chance are you trying to put this new download on a different computer then the one you first installed as a Pro Member. In other words are you trying to install a second ARC program on a second computer? I had an issue doing this. I hope it was just a problem I caused and not a bug. Let me know.
Hi Dave and DJ, I'm happy to say I was able to install the upgrade. I see what I did wrong after reading above. Thank you both
