MSI installation failure causes installer hang...

On a Windows box, if an install fails (say a service fails to start because of a missing dll), normally MSI would roll back the installation. Meaning that it would try as best it can to put things back the way they were before the install started.

On ReactOS, none of this happens. The GUI sort of freezes, and no longer responds in any way to anything. I can kill msiexec from the task manager, but that doesn't fix the underlying problem.

I realize that it would probably be hard to fully implement rollback, but I wanted to make sure that it was on the radar so that it eventually got done.

I don't have a good testcase handy right now, unfortunately..
