Problems with the installation / certificate of our air application

[jedding]

In 2014 we developed an Adobe Air application for a customer. It made database searches in a sqlite database (on DVD) possible. In 2014, we acquired a certificate from GlobalSign Ltd to develop the application.

In 2018, the application could no longer be installed, with the note that the certificate had expired. If I remember correctly, there was a note on the Adobe website at the time how to solve this problem by modifying a file in the .air application. Unfortunately, I can no longer find any of this on the Internet today.

In the meantime, the error message has changed during installation. Now it says: "Sorry an error has occurred. The application could not be installed. Try installing it again. If the problem persists, contact the application author." Unfortunately, I cannot find any information on this error message that will help me further.

Our customer now wants us to produce a new DVD with a functioning installer and is concerned that problems will arise again after a short time. Has anyone had similar experiences? Can anyone help me further?

I've never signed an AIR app with a GlobalSign certificate myself, but here's a thread about it over at the Starling forum: https://forum.starling-framework.org/d/21724-globalsign-native-installer-signing

You could also ask HARMAN for help, now that they're in charge of AIR.

Thank you very much for your reply. I'll try Harman!

Just for here in case anyone here knows the answer (maybe even from adobe themselves):

If I understand it correctly, the thread is about a different problem. At first there was no problem with the certificate, neither on a Mac nor on a PC. About 3 or 4 years after the software was released, the installation message said that the certificate had expired.
I assumed that the certificate was valid for one year, which meant that I could use it to certify / publish the software within that one year. Even after this year, the software should have unlimited installability with a valid certificate.

Signed adobe air apps using certificates are only good for a limited number of years before you have to migrate the signed adobe air app to a new certificate.

You will need to resign the adobe app to be able to reinstall the adobe air app. After a few years, depending on the length of your certificate, you will have to migrate the signature to a new adobe air app in order to let people install the app. Once the app is installed the certificate can be ignored. it is only when you are installing or updating the adobe air app that the certificate is needed.

As an extra head ache the latest mac os version now requires that you notirize your adobe air app with them (apple) in order to install it. so that means you would possibly need two certificates... one global certificate and one mac certificate. I'm not sure if you can bundle those two certificates together or not. actually working on that right now.
