Hi，

I am a fresh man. I have created a basic msi project. I want to append some value to system environment path. How to do that?

Thanks,

Try to look into custom action part which should help you.
May be you could use InstallScript or VBScript to achieve your requirement.

Actually, Windows Installer (MSI) provides built-in functionality for modifying environment variables. In InstallShield, please see the Environment Variables view.
