Most missing DLL issues occur because the driver package was corrupted or incomplete. Disconnect your ZKTeco USB fingerprint scanner.

Never download libzkfp.dll from third-party "DLL fixer" websites. These files can be injected with malware. Always extract it directly from official ZKTeco SDK distributions.

To use this library in a Windows environment, it must be correctly placed and sometimes registered: Placement:

Always call the termination and device-closing functions ( ZKFPM_CloseDevice and ZKFPM_Terminate ) when your application exits. Failing to release the handles will lock the USB port and require a system reboot.

Alternatively, ensure they are in the Windows system folders ( System32 for 64-bit or SysWOW64 for 32-bit components).

Alternatively, you can copy it into your system folders: C:\Windows\System32 (for 64-bit systems running 64-bit applications) or C:\Windows\SysWOW64 (for 64-bit systems running 32-bit applications).

An application error stating "Attempted to read or write protected memory" usually points to memory leaks.
