In trying to track down other 2.3.2 issues, I am trying to re-install to the same disk as a previous install. This fails with a "red screen" with the attached message.
At this point, all actions just return to the same screen.
This is the 64-bit version, running in an ESXi VM, and on the initial screen, I selected: Install Zentyal 2.3-2 (delete all disk)
Cheers.
