Bluestacks when installing apps creates shortcuts on the desktop (ink files) if I look at the properties of the shortcut the location path and the execution parameter of the app in question is this:
"C:\Program Files (x86)\BlueStacks\HD-RunApp.exe" -json "{""app_icon_url"": """", ""app_name"": ""Fappy Bird"", ""app_url"": """", ""app_pkg"": ""com.flappybird.tapping""}"
