Technical WotLK MacOSX "can´t be opened"

[Tatsuril]

Running on a 2010 iMac with MacOS High Sierra 10.13.6, clicking the app to start immediately prompts a window - "The application can´t be opened."
Can my system even run it? used to run original all the way to Mists.... any help would be much appreciated.
Cheers.

Thank you very much, worked perfect and runs better than the original did back then on the same machine, somehow.
cheers!
