SetLicensemultiple times is not harmful but wastes processor time.

Aspose.TeX offers an alternative licensing mechanism called Metered Licensing, which allows customers to be billed based on their usage of the API features. Applying a Metered License is as simple as applying a pair of cryptographic keys. For more information, please refer to the Metered Licensing FAQ section.
To set the public and private keys of a metered license, you can use an instance of the Metered class, as shown in the following example:
1# Set metered public and private keys.
2Metered().set_metered_key('<type public key here>', '<type private key here>')
