Hi,
it's complaining that the "administrator" user doesn't have a desktop folder and it's unable to create one.
Unable to create shortcuts in ~administrator/Desktop/: directory does not exist
Problem creating shortcuts in ~administrator/Desktop/
If you want shortcuts, try:
Create the folder ~administrator/Desktop/
Rerun the installer in the same directory where you have your install, don't select any more components, and let the installer complete.
Let me know if this fixes your problem.
