ThingWorx 7.4 introduces a new licensing system. A license file (license.bin) needs to be placed in the ThingworxPlatform folder. A new license file is also required if you upgrade from 7.4 to a major or minor release (not service pack-level releases). For example:
• If you are using version 7.3, a license is not required.
• If you upgrade from version 7.4.1 to version 7.4.2, a license upgrade is not required.
• If you upgrade from version 7.4.3 to version 7.5.2, a license upgrade is required.
Paid customers would have unlimited use of entities for 7.4.0. As currently a license file is locked to version rather than SCN/host and is part of download package on PTC Support, customers can use the same downloadable for multiple instances.
Developer Trial Edition provides a constrained license file (5 users, 100 things, 120 days), and the license file is part of on premise download package on Dev Portal.
Developer Trial Edition for Manufacturing (Kinex) provides a constrained license file (5 users, 100 things, no Composer access), and license file is part of download package on Kepware Portal.
A new Licensing Subsystem is now available.
Licensing subsystem services include:
-AcquireLicense– service allows for retrieval of feature entitlements in license.bin, used when new license dropped in folder (no need to instance restart)
–GetCurrentLicenseInfo – returns info on current license file
–GetRemainingDaysInLicense –used for trial editions
