Don't use variables. Process the PlanPackageBegin event and tell the engine the state of the package.

I've created a custom GUI through WPF and need pass back to the WIX bootstrapper app, variables that I set in the C# application. Here is my C# function that calls the Bootstrapper app private void InstallAExecute() { IsThinking = true; Bootstrapper.Engine.StringVariables["AToInstall"] = "A"; Bootstrapper.Engine.Plan(LaunchAction.Install); } and in my Boostrapper app, I have the following element <Variable Name ="AToInstall" bal:Overridable="yes" Value="A" Type="string"/> declared above my BootstrapperApplicationRef element. Then in my element Chain, I would like to add a conditional to trigger a particular msi to be installed when the variable satisfies the condition. This is what I have in my chain, but I think my syntax is incorrect. <Chain> <PackageGroupRef Id='Netfx4Full' /> <MsiPackage SourceFile="..\Path\To\Installer.msi" Id="InstallationPackageId" Cache="yes" Visible="no" InstallCondition ="AToInstall=A"/> </Chain> Any idea where I went wrong? -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Passing-Variables-from-C-custom-BA-to-WIX-tp7596113.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Infragistics Professional Build stunning WinForms apps today!
