First, Happy 2018 to all of you!

Last few days I have been struggling to install the BIAB 2018 update for my current 2016 version. I purchased the dowload version, not the physical disk. Part of the struggle was due to the fact that the complete BIAB 2016 was on my internal SSD, while I now wanted to have 2018 program on my SSD, and Drums and RealTracks files on an external drive.

Thanks to the assistance of several people on this forum I think I managed to do that properly. After a few mistakes I finally downloaded the program to my internal drive and then moved RealTracks and Drums folders to an external drive. The program on my internal drive is now only 15Gb. I am about to activate the 2018 update. In light of this I have a few additional questions:

- I made a backup copy and a full copy of BIAB 2016 before upgrading to 2018. Do I still need these? Or will a backup of 2018 overwrite 2016 anyway (and how to do this?)
- Would it make sense to download and install all RT and RD files again to be sure I am not missing any of these during upgrade? Or does the program have a facility to check for this?
- BIAB 2018 has video’s etc. now. Should I install these in a separate folder again?
- Does the 2018 program have three activation codes again? And if so, how does the 2016 activation relates to the 2018 one(s)? Will activation 2018 replace 2016? I have only one left for 2016.

Thank you
