I downloaded the installer and ran it. It took 2 hours to download the 23gb file. The files were iso files. I clicked on Kontakt 5 iso file and it opened the files in my cyberlink power togo software and I ran the exe. same for Kontakt 5 bundle and they both installed. When I tried the same for Kontakt factory library I get the message (please run this installer from the original dvd. Why won't this one install?
