QuietSimple upgrade freezes at Upgrade Progress screen

Question

I have a SQL Express upgrade running from a config file with QuietSimple=True.

The upgrade freezes at the end of the  "Upgrade Progress" screen.

It reads "Setup process complete" and shows "Database Engine Services" and "SQL Writer" installed successfully.

The Next and Cancel buttons are grayed out.

Any ideas why?

Answer 1

Same here...

Quietsimple=True
disables every button and at the end the user can't close the form.

Patch needed, please.
