I have a .msi installer built with Visual Studio 2008. It runs some custom code based on the .NET Framework System.Configuration.Install.Installer class. In my custom code I need to knowwhether the user selected Everyone or Just me on the Installation Folder dialog. There doesn't seem to be anything in the Context.Parameters collection that indicates which option the user selected.

This is the ALLUSERS (cases-sensitive) property in Windows Installer. If you pass it as [ALLUSERS] as part of your CustomActionData you'll see its value. It'll be 1 for a 'Everyone' install (per-machine).

It is a property, not a parameter.

Thanks for replying. I understand that InstallAllUsers is a property. But a property of what? How can my installer code access this property?

useCustomActionData Propertyto pass properties to your custom action

That's the connection I hadn't made yet. Thanks for your help.
