Hi everyone,

About win\_package, in the official document, it mentions: product\_id value is ignored if path is set to a local accesible file path and the package is not an exe.

So, if I want to install MSI package, and I specify the path to a local accessible file path, then I don’t need to set product\_id, correct ? If I don’t set product\_id, how it can know if the package has been installed? by searching for the InstallSource in registry?

If it’s an msi, the module can scan the package itself to get the product\_id. If it’s an exe then it would need the product\_id or one of the creates\_\* options to try and add some idempotency.
