Our old installer is starting to show it's age, and for some time now we've been working on a new one using the Windows Installer engine. This change has several advantages. Windows Installer is the native install system on the platform, it provides more powerful network installation options, and it allow us to translate the installer to more languages. But it has drawbacks as well. Windows Installer is not pre-installed on older Windows systems, and the package will be a bit larger. The transition has to be made sooner or later, and we think that the advantages now outweigh the disadvantages.
