Cubik Studio

I downloaded the Cubik Updater for Mac but i can't open it. (It says: "The application "CubikUpdater.app" can't be opened") I searched for similar problems in this forum but the solutions i found didn't work at all. I tried on terminal: " chmod +x path_to_app/CubikUpdater.app/Contents/MacOS/CubikUpdater " and " chmod +x CubikUpdater.app/Contents/MacOS/CubikUpdater " but it always says "No such file or directory"
Here is some information about my Computer:
- MacBook Air (2013)
- macOS Catalina (Version 10.15)
can someone help me?

Where it says "path_to_app" you need to change that to the actual location of where the file is.
