Hi, My InstallShield project also having multiple configurations. For your case, I have changed the "Default Product Configurations" to where I need to map the Visual Studio solution configuration and then created VS solution configuration. Now it will create under the specified default product configuration. But I am facing very strange issue in build releases, - In my project, I am having 3 product configurations and each having one 'Release'. So, my solution file(.sln) file having 3 SolutionConfigurationPlatforms. - If I am changing the "Default Product Configurations" to any other configuration, It sets the 'postSolution' value (in .sln file) for all 3 release as current default productconfiguration release. - For example, If I set the "Product Configuration 2" as my default, then it sets the "Release 2" configuration for other 2 product configuration releases. Is there any article available for this kind of build configuration? or else, anyone please share the solution for this issue? EDIT : What are all the parameters I need to pass in MSBuild command line to build 3 different configurations?
