The method generally used is this (precomp+msc+srep), as he said Razor do not using reflation.
Examined the game RIDE compressed installation of 8.3GB, 25GB uncompressed.
The workbook is created ... "C:\Users\Name\AppData\Local\Temp" through installing InnoSetup.
Inside the Game installation folder during extraction, it creates a temporary folder (temp) with most of of the game files converted to *.DDS (The DDS files are in raster image format used by Microsoft DirectX to store textures and environments.
These files can be stored uncompressed and compressed pixel formats. They are sometimes used for storing backgrounds for the Windows desktop or backgrounds, as well as for texturing models of video game unit).
In mid-installation, the files *.dds, are reconverted in the original structure of the game files and copied/moved in their original path of game.
For those who are curious or interested i posted the temporary working folder with files and methods used for the complete installation.
