Apply a license key in IronOCR

The license key is a long string that ends with an expiry date. Please ensure this is copied correctly, with no spaces.


The most robust method of applying a license key is directly in your code, before the library is called.

IronOcr.Installation.LicenseKey = "IRONOCR-MYLICENSE-KEY-RENEW.SUPPORT.01.JAN.2050";
