If you’re jonesing for the CHM version of the Softimage User Guide, it’s available as a documentation extra on the wiki. Here’s the direct download link. Softimage won’t use this version, but you can use it for your reading and browsing pleasure.

To open the CHM from scripting:

# Python
import subprocess
sCHM = "C:\\Users\\blairs\\Downloads\\xsidocs_2012\\xsidocs_2012.chm";
subprocess.Popen( "hh.exe " + sCHM )

// JScript
var oShell = new ActiveXObject("WScript.Shell");
var sCHM = "C:\\Users\\blairs\\Downloads\\xsidocs_2012\\xsidocs_2012.chm";
oShell.run( "hh.exe " + sCHM );

' VBScript
set oShell = CreateObject("WScript.Shell")
oShell.run "hh.exe C:\\Users\\blairs\\Downloads\\xsidocs_2012\\xsidocs_2012.chm"
