"Access Denied" error guest: 2003 32bit on host vista 64, professi

Trying to install a windows server 2003 virtual machine on my vista 64x
operating system (pro). It installs, barely, but when i try to apply service
pack 1 i get a really informative error message:

"Access denied" and the service pack backs itself out.

The system erorr log says

Event Type: Error
Event Source: NtServicePack
Event Category: None
Event ID: 4373
Date: 7/15/2009
Time: 4:51:31 PM
User: TECHSVVM\Administrator
Computer: TECHSVVM
Description:
Windows Server 2003 Service Pack 1 installation failed.
Access is denied.

Any ideas would be greatly appreciated.

The first thing I would check is your installation media

Cheers,
