Initialization failed message

How do I resolve an "Initialization failed" message when trying to open a new H&R Block tax prep app?

I downloaded the app twice and from two different sites (first from amazon.com, then from H&R Block). I'm able to extract from the .dmg image, and place the app in my applications folder. But when I try to open the app (to actually use it), I get the "initialization failed" message (copy attached below). I've looked at my permissions but all seem in order, and all my other software works fine for all my iMac's users.

I guess I don't understand what the message (in obscure language) is telling me. I hope someone can decipher its meaning--at least before April 15th!
