You can try VbsEdit. Get the latest version from Adersoft's VbsEdit http://www.vbsedit.com its a small download but it is a powerful tool to create and edit vbs files and convert them into executables without unpacking to temporary folder. (unless you get an old version like version 4.x.x.x) I've been using this program since 2008, and it's free to evaluate forever but comes with a reminder to activate and each time you Start your script from the vbsedit window you will have to wait a few seconds, Or you could purchase it for $60 to remove those minor annoyances.
Unlike ScriptCryptor, the converted exe won't have any limitations if you are still evaluating, it will run without any unwanted additional windows.
