No sure it will solve your issue but, the pinwheel as you call it can usually be solved by repairing the ACLS and disk permissions.
Boot on recovery partition and go to the tool menu, select change password. A window will open ignore the reset password fields, go to the bottom of the window and click on repair ACL.
Then when completed select disk utility and repair the disk permissions, reboot and retry.
Still doing the same thing. On a good note my Mac is running much faster. It locks up as soon as it starts retrieving install.
I have the same problem on OSX 10.9.3
and on OSX 10.9.4
The installer freeze at 0%
