Can you sandbox the app/block access to Adobe's servers, so that it doesn't get their deprecation command?
If I could "sandbox the clock" for this specific application, that might work, but I don't think that it is possible.
For now, I tried patching the timestamp in the binary as suggested by jtvjan, since I saw it before your post. It works, so I'll stick with it for now. But I'll be sure to try this RunAsDate when I need something similar in the future.
