I've got Komplete 13 and Reaktor 6, but native Access tells me Reaktor 5 isn't installed - and gives me the option to do that. But, installation fails with the message "The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance." Am I being lead down a road I don't need to go since I'm already using Reaktor 6? I've tried installation several times on both the parent computer hard drive, and my external hard drive.
