If I download a 6.0 or higher then it won't show up or work for me. Otherwise the icons look the same, at least in my software. The pes designs don't say pes v1 or pes v4 unless the digitizer has kindly added that information.
If you have had upgrades you could have a higher number than originally used. There is a way to tell what your machine takes but you have to read the manual to figure it out. The older your machine the lower your pes version number is.
