Resolution

• You need to make sure the user running the Jenkins Master/Slave where the command is executing has C:\Windows\System32 in it’s PATH variable.
• To add this to that user’s PATH, right click on My Computer then select Properties. Click Advanced then click Environment Variables.
  Scroll down to PATH and add C:\Windows\System32 to it.
