To prevent unauthorized usage, the update file has been password protected. The password is the 13th Glossary term defined in the CD-ROM SpeedTools User's Guide. Additionally, the password/term must be typed in using EXACTLY as it appears (including Capital and lower case letters). To point you in the right direction, the 1st term to appear in the glossary is "Address".
The update file is compressed. To open it, double click on the "CDST 3.9.4" file. Type in the password as instructed above and that's it - you're ready to install the update.
Additional Note: We frequently rotate which Glossary term is used as the password. So, please review this attached document again should you download a future CD-ROM SpeedTools version updater.
