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

IronXL.License.LicenseKey = "IRONXL-MYLICENSE-KEY-RENEW.SUPPORT.01.JAN.2050";
py
PYTHON

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

IronXL.License.LicenseKey = "IRONXL-MYLICENSE-KEY-RENEW.SUPPORT.01.JAN.2050";
py
PYTHON
