Having a problem with FNIS install

FrogLord007 · September 4, 2017

I'm trying to follow the instructions for the installation of FNIS for Mod Organizer as follows:

Download FNIS using the "Download with manager" button.
Open the 'Downloads' tab and double-click to install FNIS Behaviour 6.3.
Select the 'Manual' option and expand the FNIS Behaviour 6.3 label using the arrow icon to its left.
Right-click the 'Data' label now visible and select "Set data directory".
Message at the bottom of the dialog changes to read: 'Looks good'.
Hit 'OK'.
A dialog should appear if you already have a previous version asking to 'Merge, Replace, Rename or Cancel'. Select 'Rename' and rename it to something specific.
At this stage the FNIS Behaviour 6.3 and any previous versions will be installed together.
Deselect any previous version of FNIS Behaviour and activate ONLY the FNIS Behaviour 6.3 and any animation packages you want.
-----IMPORTANT----- : If you have already set up FNIS in the 'Executables' list and created shortcuts either on the toolbar or the desktop, these will be pointing to the wrong generator and will produce errors.
Modify the list to point to the correct executable and ensure you save this by pressing, "Modify".
You can now run this tool via the 'Run' drop-down selection box or via a shortcut and FNIS will run and update the animations.

Things to keep in mind:

If you choose to overwrite the previous installation or replace it with the new, you can not switch back to 5.2 without installing it again.
If you follow this preferred method ensure you deactivate the 6.2 version first or ensure version 6.3 has a higher priority or else you will have version mismatch errors.
Modify all existing shortcuts and executable paths to point to the current version.
I'm fine, until step three. There is no manual option. I can right click to set data directory, but Mod Organizer still gives a red message saying "no game data on top level".

If I continue any way it warns me that it was probably not set up correctly, giving me the option to either ignore or cancel.

Are the instructions old or wrong, or am I an idiot and missing something obvious?
