Invalid Class String
To fix this, you have to re-register Microsoft's JScript.dll. You can do this by first closing any instances of IE, then opening a command prompt as Admin (under Accessories, right click Command Prompt and select Run As Administrator).
At the command prompt, type the following strings:
c: [Hit the Enter Key]
cd\ [Hit the Enter Key]
cd windows\system32 [Hit the Enter Key]
regsvr32 jscript.dll [Hit the Enter Key]
--A dialogue box should pop up saying: "DllRegisterServer in jscript.dll succeeded."--
That should do it. There is a chance you may have to log off and on before it takes affect, but all my systems were fixed without logging off or rebooting.
