Trying to Use a ForEach Loop to get a product version off of an .exe, then based on that version, execute a batch of functions

Thanks in advance for taking a look. I just wanted to see what someone else might do to get this working correctly. Very new to PowerShell and Python, so I am just trying to live in it right now as I work.

This script is a little side project.

    function EXEversion {

    $prod1 = (Get-item "Path of exe").VersionInfo.ProductVersion
    $prod2 = (Get-item "Path of exe").VersionInfo.ProductVersion
    $prod3 = (Get-item "Path of exe").VersionInfo.ProductVersion
    $prod3 = (Get-item "Path of exe").VersionInfo.ProductVersion
    $MyArray = @($prod1, $prod2, $prod3, $prod4)

See my Foreach loop below:

    foreach ($item in $MyArray){
        if ($item.VersionInfo.ProductVersion -eq 15.9...)
    {
    # Here is where my other list of functions would go that delete certain items #
    }

        }

    elseif ($item.VersionInfo.ProductVersion -eq 16.0)
        {
         # Other list of functions dedicated for if this specific version is found)
        }
    }
    

Unfortunately I know my indents and format is all wrong, I am super new to PS and still learning proper format. I think I may be close, and it does work to some extent, but not correctly and not the way it needs to. Just wanted to see what someone else might do instead.
