I can’t find a way to uninstall this.
Not in the control panel.
And not when I run the setup again.
How can I uninstall?
Are you only concerned with removing the file from your disk, or are you also asking about an ability to switch from the local file back to the online file?
Both of course.
In the meantime I found the containing folder.
Renamed it.
Online help works again.
I really think there should be an uninstaller.
So Rhino automatically reverted to online when it couldn’t find the offline?
If so, that sounds like a good thing.
