For those of you who don`t grace the NI Kontakt Forum, heres a post from Julian R. explaining how to install..
I just want to clarify the update procedure.
1. Go the the shop and by the update (Users in the grace period will get a seperate download link).
2. At the end of the purchase process there are files to download
3. Download the KONTAKT installer and the DFD installer
4. Install the software
5. The sales department will automatically send you your serial number.
6. Perform the registration using the registration tool in the KONTAKT program folder. The registration key will be send to you by register@nati
7. Start the application
On some PC systems the installation does only work properly after prior uninstall of the KONTAKT 1.X version.
At this very moment the mailing and authorization process on our server runs a bit slow - so please have some patience.
I had a bunch of problems but after a complete uninstal and reinstal everything works like a charm. BWT I havent tested it much but already i like 1.5 better (LARGER FONT SIZE option!!)now i wont go blind..Rich
