Hi BluueSpruce,
I went ahead and resent your email message as well, and can download the latest version from the link provided.
To answer your questions, for the foreseeable future all updates to PC-Doctor Toolbox are provided without an additional charge, and will be provided automatically by the software (version 6169 and up). However, you are correct that the version you have does not include the automatic update capability, and will require a manual update for the purchasers of the initial version.
Please let me know if you require any additional assistance, or have any other questions.
Thanks,
Kris
