Here is the recommended path to get the SDK:

To solve this problem without using a standard system installer, developers can use two approaches: The DPInst Utility Method zkfinger sdk 50 download portable

ZKFinger SDK 5.0 is a legacy yet widely deployed biometric development kit designed for ZKTeco fingerprint recognition devices. Unlike modern SDKs that utilize standard USB drivers, ZKFinger 5.0 relies on proprietary communication protocols. This paper addresses the feasibility of creating a "portable" deployment—a common request for kiosk systems and USB-distributed applications—and outlines the technical prerequisites required to achieve it.
