As you suggest, Bob, I found that the right button is being shown, but
MSI isn't showing the shield. It appears to be because
MsiRunningElevated being set in the MSI (c) section when in maintenance
mode instead of MSI (s) like it is for the original install.
I don't know why MsiRunningElevated is set this way so early, because it
isn't really running elevated. That is, I'm not prompted for elevation
until I proceed with the Removal. It seems like a bug in MSI to me, but
perhaps it was required for other reasons. I found a thread in wix-users
from 2007 ("Shield Decoration on buttons") that discusses this, but
doesn't really answer why MsiRunningElevated got set so early.

I launch the installer without elevation (no UAC prompt), and after I
click the Remove button, it pops up with UAC prompt. It seems that both
of these indicate that the uninstall didn't already have elevated
privileges at the time the Remove button was displayed.
I am wondering if this has something to do with ALLUSERS not being set
up at this point in maintenance mode. Recall that I do have a simple
<Property Id="ALLUSERS" Value="1"/> under the Product element so I
expect that it would be.
I'll do some more digging into the log and try to determine whether it's
MSI hiding the shield or the conditions showing the wrong button (e.g. I
can simply change the text on one of the buttons to determine this).
I'll post back with what I find.
Thanks, Bob.
