Yep, basically

SET CLASSLIB TO REGISTRY ADDITIVE
oReg = CREATEOBJECT("Registry")
IF oReg.IsKey("VBScript.RegExp")
  * Version 2.0 of the WSH is installed
ELSE
  * Version 2.0 isn't installed, but 1.0 might be
ENDIF

In order to check for 1.0 you could check for something like the WScript.Shell or Scripting.FileSystemObject.
