How to install Nexpose Community so it will run?

I've used Nexpose Community occasionally for a number of years.  Now I'm trying to get it installed and running.  But, the browser gives this response:
Can’t connect securely to this page

This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website’s owner.

Your TLS security settings aren’t set to the defaults, which could also be causing this error.

I'm not sure how to deal with this.  I've already tried a few TLS settings but to no avail.
Any suggestions?

I've tried this on the Windows 7 computer I used before, a Windows 10 computer I've used before, another Windows 10 computer and a Linux installation on a VM.  All act more or less the same way-although there have been "some" differences, they all quit.  The KEY is never asked for...

Download and run IISCrypto. It will allow you to easily make changes to your server's TLS settings.

The error above seems a little ambiguous but I think if you use the PCI preset in IISCrypto you might be OK.
