Tested that one before I posted. Fresh install of the latest version. It runs, but doesn't play swf files. Gives the image at the end of this post, both for the previous .swf files I've tested and for a freshly downloaded copy of this game.

Ran it through Run As Date with a date from last year and it runs fine. Meaning its not a problem with the instalation of the player, its the general flash kill switch, descriped here.

Downloaded the latest version of Ruffle as well. It doesn't support the ActionScript in the file I had been using as a test, but it runs this game fine. It ignores the kill switch for flash content that was in Windows update. Swiff Player doesn't. Swffileplayer doesn't either.
