Well… microsoft’s at it again.
If you don’t do the registry key hack explained at: http://www.windowsreference.com/general/error-there-is-not-enough-disk-space-when-installing-sp3/
1. Click Start – Run – Type “regedit” and press enter.
2. Navigate to
3. In the right pane, Right-click and select New – String value
4. Name it as “BootDir” and set its value to “C:\”
You will get a dreaded "There is not enough disk space to install Service Pack 3"
Obviously, i’m not an idiot and i had more than 4MB of space that the error message told me i was missing.
I guess it needs a registry to tell it where…. C:\ is… i don’t get it. Anyways, its fixed and SP3 is getting on my macbook right now
