Please report non-working links.

- portable version for Windows needs no installation - simply extract the zip-file inclusive all subfolders into a new folder on your harddisk or pen-drive and start blender.exe from there.

- regular version for Windows 32bit/64bit - delivered zip-file contains only modified Blender executable and libraries, so you will need regular Blender 2.49b and Python 2.6.x_32bit installed on your system. Extract the content of CAD-edition zip file into your Blender 2.49b installation folder. To preserve the original blender executable change its name to "blender_org.exe" before.

- regular version for Linux 32bit/64bit - extract zip/tar.bz2-file into a new subfolder "BlenderCAD" in your home directory and start from there. Newer Linuxes (ubuntu 11.04 and higher) do not support python 2.6 but 2.7, so choose proper CAD-edition Py2.7 version instead. More details
