-nowin32manifest (Visual Basic)
Instructs the compiler not to embed any application manifest into the executable file.
When this option is used, the application will be subject to virtualization on Windows Vista unless you provide an application manifest in a Win32 Resource file or during a later build step. For more information about virtualization, see ClickOnce Deployment on Windows Vista.
