This structure is used in the new license generator functions (with the "Ex" postfix) to give more flexibility to WinLicense to extend the restriction features in upcoming versions of WinLicense. Notice that all fields in the structure are defined as 32-bit length (except the SYSTEMTIME fields) to simplify the migration of this structure to non common compilers.
IMPORTANT: Before calling a license generator function which uses the sLicenseFeatures structure, you must initialize the whole structure to ZERO and assign the sLicenseFeatures.cb field to the size of the structure itself. If you don't initialize the structure to ZERO, it might contain spurious data from memory which could assign non wanted restrictions to your licenses.

Contains the size in bytes of this structutre. This field MUST always contain the size of the sLicenseFeatures structure to help WinLicense determine the number of features available when there are different version of the sLicenseFeatures structure.
Number of days to restrict the use of the generated license key.
If this field is zero, the generated license key will not have days expiration.
Number of executions to restrict the use of the generated license key.
If this field is zero, the generated license key will not have executions restrictions.
SYSTEMTIME struct that holds the expiration date for the generated license key.
If this struct is all zero, the generated license key will not have date expiration restrictions.
Country ID value to restrict the generated license key to a specific country.
If this field is zero, the generated license key will work in every country.
Runtime restriction in minutes for the generated license key. The registered application will only run Runtime minutes in every instance in memory.
If this field is zero, the generated license key will not have a runtime restriction.
Global time restriction in minutes for the generated license key. The registered application cannot be executed more than GlobalTime minutes in general.
If this field is zero, the generated license key will not have a global time restriction.
Expiration date to install the license. The user must install the license before the specified InstallDate. If a user tries to install a license after InstallDate the license will be rejected.
If this struct is all zero, the generated license key will not have install date restrictions.
Maximun number of instances running inside a network.
If this field is zero, the license will not have restriction inside a network.
This field is only used by Dynamic SmartActivate keys. When this field is set to 1, the generated SmartActivate key will contain the user information embedded inside the SmartActivate serial number.
If this field is 0, the user information will not be embedded inside the SmartActivate serial number.
This field specifies if the license creation date will be embedded inside the license. The creation date of the license can be obtained in runtime via the function WLRegLicenseCreationDate.
If this field is 1, the creation date will be inserted inside the generated license.
If this field is 0, the creation date is not inserted inside the license. In that case, WLRegLicenseCreationDate will return false.
