I'm using SD3 VR version (latest 3.2.3) and it doesn't load SDX libraries (Core, NY1, NY3). All of my EZX and SDX libraries are in the same EZX folder. All of the EZX libraries show properly though.

Windows 10 64bit
i7 6th gen
16G Ram
1TB SSD

 

Do they say Full Installation under settings>manage libraries?

No? Try setting a different path in the folder tree until it does.

 

Maybe they are not updated?

 

No msg from them. Do you mean creating a new folder for SDX?

 

How to update it?

 

Default location for standalone programs is C:\Program Files\Toontrack\name of product\*.exe
Default location for Toontrack library and data installation is - C:\ProgramData\Toontrack
Default location for VST is system default - C:\Program Files\Steinberg\VST

This is what the V.R. installers default to unless otherwise changed in registry settings.

The "Home" folder for EZdrummer and Superdrummer are the same - C:\ProgramData\Toontrack\EZdrummer
This is where MIDI, EZX and EZdrummer databse are stored.

SDX are stored in the default folder of C:\ProgramData\Toontrack\Superiroir Drummer 3
This structure should be maintained even when located on a different drive.

The registry entries must also point to where the libraries & home directory are located.

Spoiler: See images below for examples.
