Terminal output wine-1.9.24-105-g1d3b944

I have a clean WoW64 prefix set to Windows XP mode and I am attempting to
install .NET 3.5 SP1 in this prefix.

The installer manages to download everything it needs and will start installing
everything only to fail at the very end of the installation process with a
"Setup Error".

I don't receive and crash messages in my terminal so there's no backtrace to be
had.
