Licensing with Year
Mode and Compatibility
Licensing with year mode is a major improvement to the ElecKey system. It enables the licensing system to support
multi-year period limit, up to 31 years. However, it is not backward
compatible. The following describes the details, including compatibility
information.
Period Limit
You can set the period limit when you want to protect and distribute
your application as a time-based license. The period limit is available two
modes:
·
Day.
The Day mode refers to MaxDay of Key Properties,
which specifies the maximum number of days allowed (1 to 998).
·
Year.
The Year mode refers to MaxYear of Key Properties,
which specifies the maximum number of years allowed (1 to 31), given that one
year is equal to 365 days.
The licensing system uses MaxDay and MaxYear to calculate the period limit in days, or called MaxDayPeriod as:
MaxDayPeriod
= MaxDay + (MaxYear * 365)
From the above formula, when using the Year mode, you can also specify MaxDay as the remaining days of a year (0 to 364). The
table below summarizes the use of MaxDay, MaxYear, and the result in MaxDayPeriod.

MaxDayPeriod = MaxDay + (MaxYear * 365) DayCountPeriod = DayCount +
(YearCount * 365) DayLeftPeriod = DayLeft +
(YearLeft * 365) It is recommended to use the above
properties when refer to the period limit, instead of using MaxDay, DayCount, and DayLeft. For more details, see the KeyCheck
API Reference. |
Compatibility
Licensing with year mode was first introduced in ElecKey
version 2.0.8.20. Since it is not backward compatible, to use this feature,
you must update and deploy ElecKey version 2.0.8.20
or higher to your system, including the protected application, KeyCheck API, LicenseGen SDK, and
Activation Server. The table below lists the files that must be updated.
