A: Yes. This classic error means the COM registration failed. Run C:\Windows\SysWOW64\regsvr32.exe C:\Windows\SysWOW64\zkemkeeper.dll explicitly, then reboot. Conclusion Installing zkemkeeper.dll on a 64-bit system is not inherently difficult—but it is a precise process that respects Windows’ architected separation of 32-bit and 64-bit libraries. The vast majority of failures stem from two mistakes: placing the DLL in System32 instead of SysWOW64, or using the 64-bit regsvr32 on a 32-bit DLL.

However, installing this DLL on modern is notoriously problematic. Unlike standard DLLs, zkemkeeper.dll is often distributed as a 32-bit component but must interact with 64-bit applications, or vice versa. A: Yes
A: The DLL uses low-level USB and network socket operations. Add an exclusion for the entire folder C:\Windows\SysWOW64\zkemkeeper.dll in your AV software. Conclusion Installing zkemkeeper
The file is the beating heart of ZK Software’s SDK (Software Development Kit). It acts as a dynamic link library that allows third-party applications—such as payroll software, custom attendance portals, or biometric management tools—to communicate with ZKTeco fingerprint and facial recognition devices.
