To use IronPDF in a live production environment without watermarks or restrictions, you must apply a valid license key.
IronPDF binds evaluation keys to a specific machine fingerprint. If you change hardware (RAM, CPU, Disk) or clone a VM, the key breaks. Log into the Iron Software portal and "deactivate" the old machine to release the license lock, or purchase a key that supports floating licenses.
Even with the correct key, developers often encounter issues. Here is how to fix the most common "IronPDF license key" errors.
