Try commenting "url-exists-in-path? " and verify that tm_reduce.bat is in the
plugins/reduce/bin folder (should contains one line like:
C:/PROGRA~1/Reduce/bin/redcsl --texmacs):

(plugin-configure reduce
  ;(:require (url-exists-in-path? ""))
  (:launch "tm_reduce.bat")
  (:session "Reduce (CSL)")
  (:serializer ,reduce-serialize)
  (:scripts "Reduce"))

Then let's hope ;)
