Error message when you run a script that is encoded by using Script Encoder (Screnc.exe) in Windows Server 2003 or in Windows XP


Consider the following scenario:
  • You use Script Encoder (Screnc.exe) to encode a script.
  • You run the encoded script on a computer that is running Windows Server 2003 or Windows XP.
In this scenario, you receive an error message that resembles the following:
Script Error
Line: Line_Number
Char: Character_number
Error: Invalid character
Note The Screnc.exe script encoder uses the Jscript.dll file or the Vbscript.dll file to encode a script. The Jscript.dll file or the Vbscript.dll file is included in Windows Internet Explorer 7.


This problem occurs because the non-encoded scripts use comments as encoding markers. These comments resemble one of the following:
  • '**Start Encode** for Microsoft Visual Basic Scripting Edition (VBScript)
  • //**Start Encode** for JScript
These comments and the lines that come before them should be visible in the encoded script. However, they are invisible.


To resolve this problem, download and then install Windows Script 5.7. To download Windows Script 5.7, visit one of the following Microsoft Web sites:
