[wix-users] UI for log-in at end of install?

[Alan Sinclair]

Is there a wix UI which can gather user name/password after the binaries
are installed, then call a DLL custom action to log the user in, repeat the
process if needed (e.g. if user mistyped pw) by re-opening the same dialog
plus "wrong credentials" message, and roll back the install if login fails
or the user cancels?

If not, what's the easiest/best way to do that?

I've used the WixUI_Advanced before and added a new dialog (a couple of
years ago so details are vague) but iirc the WixUI is always run before
installing binaries, with the dialogs chained, so that's not going to work
for logging the user in.

Thanks
