Here is a thread with similar symptoms over on the IIS.net forums. Basically, the 2 things to try are:

  1. Remove the "Windows Process Activation Service" and IIS features from the computer, then reinstall them.
  2. Do an "OS Repair" installation of windows, due to the component based services catalog being corrupt. An OS Repair install would fix that.
