To upgrade to a new version of WinDriver on Windows, follow the steps outlined in Section 3.2.1, which illustrate the process of installing WinDriver for Windows. You can either choose to overwrite the existing installation or install to a separate directory.

After installation, start DriverWizard and enter the new license string, if you have received one. This completes the upgrade of WinDriver.

To upgrade your source code, pass the new license string as a parameter to WDC_DriverOpen() [B.3.2] (or to WD_License() — see the WinDriver PCI Low-Level API Reference — when using the low-level WD_xxx API instead of the WDC_xxx API [B.2].

The procedure for upgrading your installation on other operating systems is the same as the one described above. Please check the respective installation sections for installation details.
