You have more than one edition of Microsoft Visual Studio 2005 installed on a computer.

The installer may not apply the update to all editions of Visual Studio 2005 that are installed on the computer.
Also, if you use Microsoft Update or Windows Update to receive updates, the update Web site may offer you the update again.

In this case, the installer will exit after it has applied the update to the first edition of the product that the installer finds in the cache. The installer will do this before it has applied the update to the remaining editions that are installed on the computer.
