Issue installing Hallmark Card Studio v22

Check out Cardia from Addison Software in the App Store. It does not have a catalog of images but you can find any image you want on the internet and use that. It works with Mojave all the way to the latest Sequoia and is regularly updated. And it's designed for the Macintosh and only for Macintosh. No Windows nonsense. 

I’d expect a app to open directly, so what happened here is unclear. Whether the vendor didn't sign the app for some reason, or something else happened to the app, or it’s a hacked app?

For assistance with this app, check with the vendor: https://www.hallmarksoftware.com/products/Card_Studio_for_Mac/Default.aspx?preflanguage=5&rs=48

Here are the published support details:

Given the website lists the app as incompatible with macOS 15, I would look elsewhere.

Yeah, you’re not (yet) running macOS 15, but macOS 15 has been available for app testing since June; over half a year.

There are other greeting card apps, and there are greeting cards templates for common apps including Pages.

Pages templates are either free, or one price.

And it’s quite feasible to modify existing or create your own new Pages templates using your own photos, art, or otherwise.

And as mentioned, there are other apps available in the Mac app store, and elsewhere.

The Hallmark app has been an ongoing source of discussions around here.

From what I can tell Hallmark has no plan to make this program work. It was OK through Sequoia 15.1 but not after.

After using Hallmark Software for many years, I can now now only use this app on an older Mac with Ventura. Hoping the developer will make it compatible with new OS.

I'm afraid that is a poor substitute for the Hallmark app. with all its various images and wording but perhaps better than nothing.
