Thoughts about setup and deployment issues, WiX, XNA, the .NET Framework and Visual Studio
Robert Flaming has been posting a series of articles describing how Windows Installer interacts with the User Account Control (UAC) feature that is being introduced in Windows Vista. These articles contain information not included in the Windows Installer SDK topics related to UAC. So far, he has published 20 articles (linked individually below). I highly encourage any setup developer who plans to build MSIs that target Windows Vista to read this series, and to check in on Robert's blog for possible future updates regarding Windows Installer and UAC.
