We have seen a number of installation errors reported. In the next few weeks we intend to release a change that hopefully eliminates these altogether.
Meanwhile try these steps, they have solved these issues for others:
Ensure sufficient disk free space
Robocorp Lab provides a lot of libraries and automates environment handling. This means you should have a few gigabytes free to be safe in the near future. A gigabyte could be enough to install, and as you create more robots the need increases.
Ensure your Windows 10 has long filename support
This is the most frequent cause for the installation problems. Make sure the long filename support is enabled!
Open task manager (or similar depending on OS) and kill any Robocorp Lab processes as well as a all jupyter-lab processes
Uninstall completely as instructed here https://robocorp.com/docs/product-manuals/robocorp-lab/robocorp-lab-installation#uninstalling-robocorp-lab
Download and install the latest version from https://robocorp.com/download
Checking and correcting the long filename support before doing the clean re-install is important!
