Transformer cx non cas to cas

[Minjaz]

Well, before to install the nlaunchy, I need to ask some things respect to:

C) Install nLaunch

• C0) On the computer, go into the 'CAS' subfolders.
• C1) Remove the 'phoenix.tns' file from the 'nlaunch' folder if present.
  If you don't want to have the 3.6 OS on your calculator:
  
  • On the computer, rename the 'phoenix.old.tns' file in the 'nlaunch' folder to 'phoenix.tns'
  Send the 'nlaunch' folder to the root of the calculator (directly in 'My Documents').
  If you still want to have the 3.6 OS on your calculator:
  
  • Go into the 'non-CAS/nlaunch' subfolder on the computer and send the 'phoenix.tns' file to the 'nlaunch' folder of the calculator

Overwrite existing files/folders if necessary.
If it doesn't fit, remove files in other folders but in all cases keep 'ndless_ressources' and 'ndless_ressources_36' in the 'ndless' folder.[*]

I'm a little confused in part C1.....

At the begining in the subfolder CAS in nlaunchy there are 3 files: nlaunch.tns, phoenix.old.tns and phoenix.tns

First, I delete the file 'phoenix.tns' folder 'nlaunch'
second, like I'm have SO 4.3 to not keep the SO 3.6, I rename the file 'phoenix.old.tns' folder 'nlaunch' to 'phoenix.tns'

Doing this will I have in nLaunchy only two files: nlaunch.tns and phoenix.tns really?

or is there any mistake?
