I was just notified that the Windows Installer 3.0 redistributable has been posted live. 

1.  The redistributable package can be obtained from: http://www.microsoft.com/downloads/details.aspx?FamilyId=5FBC5470-B259-4733-A914-A956122E08E8&displaylang=en

2.  There is also a Knowledgebase article about this release available at: http://support.microsoft.com/?kbid=884016

3.  Finally, the SDK documentation and tools are part of the Windows XP Service Pack 2 platform SDK and are available by clicking the "Windows XP SP2 SDK" link from: http://www.microsoft.com/msdownload/platformsdk/sdkupdate/

I know a number of you were waiting for this release, so here we go.  On with better patching and command-line typing in Darwin.
