About Windows Installer, the .NET Framework, and Visual Studio.
One of several apparent improvements for the new patch wrapper is better logging support. More often than not if a problem occurred while trying to install the patch it was difficult to diagnose because there was no logs for the patch installation itself. A user would have to extract the .msp file and install it using msiexec.exe and pass verbose logging options, or would have to enabled the Windows Installer logging policy and find the right MSI*.log file in their his or her %TEMP% directory. Now all logs are created by default for both the wrapper and the patch itself.
The new patch wrapper will create a verbose log for each application of the patch, so that if the patch applies to multiple products installed on your system multiple patch logs are created. If all patch applications occur successfully the logs are deleted; any failures will leave the logs on your system which can help you and us diagnose the problems better without having to reproduce the problem just to get logs again.
The logging policy for the wrapper follows.
When requesting support for patch installation issues, be sure to bundle all these logs together. Remember that if you just double-click the patch or even just run it from Windows Update and any failures occur, you can find a directory with the same name as the patch executable in your %TEMP% directory. If you're downloading from Windows Update and don't know the name, just switch the view of your %TEMP% directory to the Details view and sort by "Date Modified" to find the most recent patch-specific temporary logging directory.
