I know that there's a method,
C++
UINT MsiInstallProduct(
__in LPCTSTR szPackagePath,
__in LPCTSTR szCommandLine
);
However, it needs a package path, then how can i get it by product code?
Thanks!

It's a lot easier to use the WindowsInstaller.Installer object but the APi is documented thoroughly (with examples) on MSDN as well as in the SDK.

Thanks.
I'm on the C++ land, and API might be more suitable for me.
I find that, by MsiGetProductInfo() with paramter "INSTALLPROPERTY_LOCALPACKAGE", I can get the cached msi file in "C:\Windows\Installer\...".
If I delete this cached file, and try to uninstall the program in "Add/Remove Program", it will look for the original msi file(which I used to install the program).
How can I get the original msi file path with API?
