What to enter for "engine" in cscript command line: It looks like "vbscript" is OK, and I've personally used "jscript".

//E:engine
Executes the script with the specified script engine. Among other things, this allows you to run scripts that use a custom file name extension. Without the //E argument, you can run only scripts that use registered file name extensions. For example, if you try to run this command:
cscript test.admin
You will receive this error message:
Input Error: There is no script engine for file extension ".admin".
To run a script that uses a custom file extension, include the //E argument:
cscript //E:vbscript test.admin
One advantage of using nonstandard file name extensions is that it guards against accidentally double-clicking a script and thus running something you really did not want to run.
This does not create a permanent association between the .admin file name extension and VBScript. Each time you run a script that uses a .admin file name extension, you will need to use the //E argument.
