Then something's still running that's using that directory or file. Have
you made sure that the shell you're using to umount doesn't have that
directory as its working directory? (And if you used 'su' to get to
root, is the user shell you came from currently in that directory?)
If that doesn't help, you can run
lsof /var/tmp/imgcreate-2A4KXU/install_root
to find out what process has that directory or something beneath it
open.

Yes, you won't be able to delete the loop device until after you've
successfully umounted, because the install root is mounted via the
loopback device. When you've managed to umount everything, the losetup
-d should succeed.
