RWTS-PDFWriter.pkg can't be opened

[pelargir]

The latest pkg version gives this security error when opened in Mac OS Catalina:

I'm not sure what needs to be done to prevent this from happening. Any ideas?

This has to do with your Gatekeeper security settings (System Preferences > Security & Privacy). Instead of double-clicking the installer package, you can right-click it and select "Open" to launch it.

Right, it's just inconvenient having to do that.

I've resigned the package, and this time I have also had it notarized and and stapled. It will now install without Gatekeeper complaining.
Thanks for prompting me to work out how to persuade Apple to notarize this.

That's incredible, thank you!
