might I give you an easy solution to supply to anyone with installation/launch problems for any game downloaded off of itch?

this program is completely free of use. it will unzip all files, allows you to pick and choose location it will unzip to (i pick the desktop each time to make it easier to get to). This program will ensure the person who downloads any file that needs to be unzipped hassle free.
@OP try using this, it should solve your problem.
side note: this program will ask for permission to become your primary program to unzip / install all downloaded items off the web. It's safe to accept it.
