If it’s EZdrummer Lite, it was most likely removed from the bundle. EZdrummer Lite has been discontinued since 2014.
I also bought Korg Taktile and it is supposed to have EZDrummer Lite included but I don’t see anything at Korg’s website. I contacted Korg support and here is the reply:
Thanks for your purchase! You’ll have to make an account on the toontrack website and you should be able to get it from there.
