The download for this workbench is large--somewhere around 1.2 gb. Finding the install exe for linux or windows isn't clear. Basically this download appears to be from a 2 disk distributable set of *.ISO files. Ignore all the distraction scripts in the core directory. Delve into
\ibm_ds410_lin64 (I downloaded the 64 bit version) . Look for a directory called
Disk1. There you will find the installer images for Windows and Linux.
Here's a visual image of what the directory will look like.
