My Exomdia Program Doesn't Work!

Hi! I am working on a program called ExomDia, a front-end for Exomizer, which in turn is a compression program to target applications for certain older computers, and am having a problem: when I right-click a file to compress then click on an option registered by my program, Win10 asks how I want to run the file. I want to compress the file, not run it. What gives? Following are the registry dumps for the target file:
