That's what I thought as well, but just out of curiousity, I attempted to install it on another machine (The heap in my sig)...and it installed fine. So it was something wrong with the original machine...which I should've mentioned, is a Macbook. Apparently you have to add something to the registry to get it to work; SP3 doesn't seem to like EFI on these Apple machines. Tried the following solution below and all is well.

This issue affects Windows XP Home Edition and Windows XP Professional operating systems running through Apple Boot Camp.

If you attempt to install this release candidate on an Intel-based Apple computer (Mac Pro, Mac Mini, MacBook, MacBook Air, MacBook Pro, or iMac) that is running Windows XP SP2 through Boot Camp, installation may fail with the error "Out of disk space".

To avoid this, manually create a necessary registry key as follows:
To create the registry key

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Setup
3. On the Edit menu, point to New, and click String Value.
4. In the text box under the Name column, type BootDir and press ENTER.
5. Right-click the name BootDir, and then click Modify.
6. In the Edit String Value dialog box, type the drive letter for your system drive, and then click OK. For example, if your system drive is C:, type C:\.
7. Close Registry Editor.

After you have created this registry key (or if you created this key when you installed a previous version of this Service Pack), you can proceed with the installation.
