MSI Installer

What all did you need for an installer? Depending on how complex you need it, I (or others) might be able to help. A couple things about installers:

• For generating vanilla MSI Windows installers, WiX is the usual means. All the configuration is stored in XML, and it can work with Visual Studio or as a standalone tool. It can do most everything, but it requires a fair amount of knowledge to do more complex tasks. Simple folder deployments are very straightforward, though.
• There's a lot of other installation systems, like InstallShield or NSIS that get used a lot due to be being relatively simplistic. Most often they get deployed as executable assemblies (EXEs) instead of installers.
• You can do fancy UI wrappers around the installers (with EXE wrappers) and some limited internal UI changes, too, but I generally wouldn't bother. There are templates that give you the standard Welcome/License/Installation Path UX.
• Building installers from non-Windows systems can be a pain. WiX requires WINE to build on Linux due to a dependency on MSI.DLL. There's a Gnome project, MSITools, that has a partial WiX implementation but finding documentation on it is a pain, so I haven't bothered looking into it.

So what did you need the installer to actually do? And is it okay if it only builds on Windows?
