updates: "0x737D" (30 Dec-09)
<QP>
SYMPTOMS
When you install updates by using Windows Update or Microsoft Update, you
receive the following error code: 0x737D

Additionally, you may receive the following error message:

SQL Server Setup cannot upgrade the specified instance because the
previous upgrade did not complete.

Note: Microsoft SQL Server 2005 may be installed on your computer when you
install applications such as *Windows Live Photo Gallery* and *Windows Live
Mail*.

[Doh! So that's where it comes from...]

CAUSE
This issue occurs because the installation of an update to SQL Server 2005
is not completed.

RESOLUTION
To resolve this problem, complete the installation of the update to SQL
Server 2005, and then enable additional updates.
