FWIW I have been beta testing tor Toontrack for years.
All you have to do is download Toontrack`s Project Manager application & run it.
It will show any TT products you own and have registered online on their site as being available & give you the option to download & install it and authorise it all automatically.
It has not been normal to try and hand- install their products in many years.
Now of course this does assume that you actually bought a legitimate version of EZ Drummer2. (
