APCC - Update License/Subscription

The APCC - Update License/Subscription window shows features that you are entitled to with your license.

APCC's subscription policy is the following:

A) Within a major point release bug fixes and some minor improvements are free. A major point release is the starting digit. For example, 1.0 and 1.9 are part of the same major point release (1.x), but 2.0 would be a new major point release.

B) Some newly developed features will require a license date within the last year of the feature's availability. For example, if new feature X is released on August 1, 2021, then it is available to everyone with a license dated one year earlier, which would be August 1, 2020 in this example.

C) If a license date makes a feature unavailable, you can purchase a subscription renewal, which will update the license date to the current date of the purchase. This will also make available any additional features added within the next year.

In the screenshot below:

1) Shows 6/2/2016 as the current license date.

2) Shows the list of subscription features enabled in the currently installed version of APCC, which is determined by the license date. In this case, none of the features are available.

3) Shows the list of features available with a subscription renewal.

4) Brings up a browser to the page where you can purchase a subscription renewal.

5) If you have a new license, you can paste it into this box. Note that for the license to become effective, you will need to restart APCC.
