I tried a lot of different things.
1) Start a brand new money file.
2) Revert to an old backup where I knew the portfolio manager was working.
3) Repair data file.
- None of these solved the problem, so it's not a data file issue.
4) Uninstalled and re-installed Sunset edition from the downloaded installation file.
5) Re-boot a bunch of times before and in-between all the above steps.
Also noticed this which makes me think I'm somehow missing some key installed components.
I think the next step is to find another PC to install it on. My current PC is managed by my company and has some security stuff going on so maybe that is part of it.
I will try the "Run as Administrator".
