Do you come across error messages popping up frequently saying that Windows Script Host can not find script file loader.vbs? Loader.vbs refers to a specific VBScript that offers an ideal environment for running scripting languages. Such components allow users to automate tasks as well as perform various operations using scripts written in scripting languages like VBScript and JScript. WSH provides a runtime engine along with a set of objects and methods that can be accessed through scripts. While using WSH many users experience issues with the execution of a VBScript file named Loader.vbs. This kind of blunder is often mistaken for malware, but it is nothing more than a stop code with the VBScript file.
