Instructions for Message Sentry Version 1.7 Text Encryption Software The Sentry17.zip file should include three files: 1. Sentry.exe 2. Sentry.wri 3. Readme.txt (this file) Place Sentry.exe and Sentry.wri in the same directory. Sentry.exe needs to access Sentry.wri. Let me put your mind at ease: Message Sentry does not alter any of your system files or current settings, nor is anything other than Sentry.exe and Sentry.wri added to your system. Happy Encrypting!
