File location from start screen

[AWS]

Hi guys,
How do I locate the actual file from the link in the start screen? For example, I just installed the netflix app. The big netflix logo now appears in the start screen and allows me to use netflix. However, I want to see whether the executed netflix program
exe is digitally signed. To this end, I have to locate where the file is located and if there are multiple netflix files in my drive, WHICH of those files is pointed to by the link on the start screen. How do I find out?
Thanks.
