Code Error 80041010 - Invalid Class

Troubleshooting Code 80041010 - Invalid Class

Introduction to Code 80041010

Error code, 80041010 occurs when you execute a VBScript connecting to WMI (Windows Management Instrumentation).  This is a spelling error check the names of the objects.  Alternatively, you could be trying to use a class that does not exist.  In particular check for plurals which should be singulars e.g. win32_OperatingSystem and not win32_OperatingSystemS.

The Symptoms You Get

The script does not manipulate the WMI object as you had hoped, instead you get a Windows Script Host error message.

The Cause of Code 80041010

Your VBScript contains a misspelled object name.  Code 80041010 is an unusual Error in that a number is returned rather than 'Syntax Error' or other message.

The Solutions

Check the class definitions in the WMI section of the your script, check for extra letters, plurals can be a particular problem, e.g. system or systemS. 

As ever, pay close attention to the line number: Line: 4.   In this case it Char: 1 is not to blame.  When none of the line can execute, the error gets charged to the first character.
