With our current release, 3.x, we have completely overhauled the software as well as made SentryPC entirely cloud-based. With this change we have also moved to subscription pricing. There will no longer be a need for upgrades, rather, if you have an active subscription you can update your software to the latest version anytime you wish for free. Just login to your account to download and install the latest version.
If you are still using our previous 2.x version you can upgrade to the latest cloud-based version for a 50% discount off your first subscription period (the first year). Just use the button below to contact our staff and request an upgrade, including your order information or current username, and we will provide you further information.
