Install hangs at "Checking System"

[MikeWalker]

I have tried to install Local by Flywheel on two different computers - both getting stuck at “Checking System” - a laptop and a desktop. I just tried again on the laptop after uninstalling the software and deleting the “Local by Flywheel” directory. The error log from the most recent attempt is:

Any thoughts on what I can do to resolve this. The version on the download file shows 2-1-2
Thanks
