What is happening inside the licence?

Transferring a licence is a complex workflow. Below are detail information.

Licence File

The CheckLicence command decides if a licence check has to to be done online or not. It depends on the settings for Ongoing Verification and Date for the next online check (set by CheckLicenceDays).

Condition in the licence file
LicenceVerification	Next Online Check	Action of CheckLicence
Off	Doesn’t matter	CheckLicence does no online check
Ongoing	Empty	An online check on the Web Activation Server is performed
Ongoing	Date is in the past	An online check on the Web Activation Serveris performed
Ongoing	Date is in the future	CheckLicence does no online check
Frozen	Doesn’t matter	An online check on the Web Activation Server is performed

Web Activation Server

If CheckLicence performs an online check then:

The ID (Serial Number) is	This happens on the Web Activation Server	This happens inside the licence file
not in the database (it is used the first time)	The ID is inserted into the database for this computer	CheckLicence succeeds and therefore grants the usage of the application. The next online check is set (in 10 years in our example) with CheckLicenceDays
already in the database and it is registered to the same computer		CheckLicence succeeds and therefore grants the usage of the application. The next online check is set (in 10 years in our example) with CheckLicenceDays
already in the database and it is registered to another computer		CheckLicence fails and therefore denies the usage of the application The flag LicenceVerification is switched to frozen. If the application starts again the Online Check is done again.
