I mean doing this in a InstallScript project so the installer would exit in the first place if it's not running with correct processor type.
I found it'll be easy if it's a InstallScript MSI project, just modify the "Template summary" field, while this options is not there in InstallScript project.
I have some requirements which could be met perfectly by InstallScript project type so I cannot git it up.
Thank U in advance for your advices.
In InstallScript you often have to roll your own behavior. In this case, it's easy: just check the SYSINFO struct for the parameters you require, and provide appropriate messaging and abort (or continue). In this case it's probably SYSINFO.bIsWow64.
