Error: Extension JsExt-Interpreter was not loaded. (HTTP/HTML script)

Hello,

 I am using windows server 2012 r2, loadrunner version 12.53 Patch-4.

 When I run a Web HTTP/HTML script through Controller, then getting these errors.  

(Error: The remote host's status is failed. Check the remote host machine [and verify that it has not crashed].   Error: Extension JsExt-Interpreter was not loaded. You are running under secure mode and this extension is not allowed in this mode.)

 However, when I run a TruClient script through Controller, then the script run without any error.

 Can anyone help me to fix this?

 Thanks
