How can I check a user's machine for Windows Installer Service BEFORE the user downloads my product setup? I'm shooting for a small download (per bus dev) and would like to be able to offer a setup with the MSI engine and a setup without the MSI engine. Any ideas? Suggestions?

If the browser supports VB Script, you could have something like this on your web page:
set objInstaller = CreateObject("WindowsInstaller.Installer")
If this results in a failure, Windows Installer is not there.
set objInstaller = CreateObject("WindowsInstaller.Installer")
If this results in a failure, Windows Installer is not there.
A general solution for all browsers would require the download of a small executable I think.

Another approach is to use a modification of the Wrapper that Microsoft offers to check for the version of Windows, verify that the Installer package is there, and install it, if not. The wrapper is really quite small (my version for NT/2000) is 169KB.
You can probably hook it up so that the client downloads only the install package needed (both are about 1.5 Meg) and then you would only have to worry about the MSI package. You would not, theoretically, need another install.
Please let me know if you would like to have additional information on this option.
