Yes and no. I am not completely where I wanted to be but fairly close.
That's on top of my head, I may have missed something since it's a while ago.
Hope it helps
For something like this, you may want to consider setting up a separate Sandbox instance that the new colleague can play with without having to worry about stepping on another user. He could also install it locally on his machine if he's running the right configuration. You would need to refer to the System Requirements to validate. Note that even though Windows 10 is not listed, many of us run ThingWorx locally on our machines under this OS. We're suggesting this as an option as the server you're referring to may be one that requires more restrictions to prevent contaminating existing data and projects.
