HI @yaronw3,
While the MSI for the tools shows up in my installation, I found that I could not get it to install the tools by executing it. So here is the method I found that worked for me.
I went to my account page and re-downloaded the AutoCAD 2018 installer. When it starts up, you will see a tab labeled Install Tools & Utilities.

Selecting that should give you the option to install the CAD Manager Tools.
Please select the Accept as Solution button if my post solves your issue or answers your question.
