Using args[] for opening files

I don’t know. I guess it is possible. Probably this is what of the few things that software installers do. They unpacked the files, create proper associations and define uninstallers instructions. You will need to do some reading on your own as I don’t have experience doing this.

You could create a bat file and provide instructions to run it. Remember you need to run this as admin. The instructions provided above were only tested in Win10. You will need to test these instructions in Win 7/8. Lastly, make sure you do proper testing, including managing 32 and 64 bit platforms separately and research in how to undo these changes in case the user needs or wants to remove them.
