## Remarks

This API attempts to acquire a license for the requested durable.
If it's the first time the device is acquiring the license, a service call is made, therefore requiring an online connection.
Subsequent calls for the same license may be faster due to caching, but the license can be invalidated at any time.
On Console, offline access requires that 'Home XBOX' be enabled for the owning account and the license must first be obtained once while online.
For PC, offline access requires that 'Offline permissions' be set for the account that owns the license and the license must first be obtained once while online.

[XStoreRegisterPackageLicenseLost](/reference/system/xstore/functions/xstoreregisterpackagelicenselost) can be used to monitor if the license obtained from this API is lost.
