Description:
Hi, I'm unable to uninstall MySQL Server 5.7 on my Windows Server 2012.
I've tried to:
 - Uninstall in "program installations" but, the progress bar during uninstall come back (like performing a rollback) to the start without uninstall
 - Try to Remove Mysql Server by MySQL Installar but the process failed with this log:

What's wrong?
Thanks

How to repeat:
I've installed MySQL Server 8, uninstalled this, installed Mysql Server 5.7.27 and try to uninstall... but it's very strange behaviour.
