SQL updates failing on WSS Developer VM

I noticed SQL updates (KB960089 but also SQL SP3) were failing to apply on the WSS Developer VM.

After many hours of frustration, I located this great blog post that helped me to overcome the issue:

In my case, the missing .msi's were from SQL Developer edition.  The missing .msp's were from SQL SP2 & KB948109.

Here's the download location for SQL KB948109:
