I had zero luck reinstalling battery 3 both from my original DVDs and the installer disc image on NI’s site. I was however able to download the two Battery 3 disc images from NI’s site and these contain about 12GB worth of Battery 3 files, which I’m going to attempt to batch convert to Battery 4 format. I’ll let you know how that goes.
In the meantime, I’ve run into a huge snag. Even though I set my applications folder as the default for my Komplete 12 library it installed everything on my external drive (maybe because I chose the external drive as the installer download location?). Anyway, I didn’t have any luck just moving that stuff to my Native Instruments application folder, so I’m having to delete all of the applications and try again.
Major PITA, hopefully it works. Native Access is downloading all of the applications again, so I won’t know for a while.
