- If using .NET Framework:
- Recommended: C:\Windows\System32 for 64‑bit DLLs (System32 is 64‑bit on 64‑bit Windows).
- Alternatively place it alongside your application executable.
If your calling application is compiled as a 64-bit executable (e.g., a modern C# or VB.NET app with Platform Target = x64), you must use the 64-bit version of zkemkeeper.dll. Attempting to register a 32-bit version in a 64-bit environment will result in
