A new version of Quicktime Alternative is available, version 2.70. Here is the new MSI file for deployment. If you want the normal QuickTime Alternative package it can be found at Codec Guide.
MSI Installer Downloads
Details on the build process can be found here at my first MSI installer for Real Alternative 1.75, the process for producing a QuickTime Alternative MSI installer is exactly the same as a Real Alternative MSI installer. As always you should actively virus scan these files if you don’t trust them.
