A missing DLL with a random-looking name in System32 is not a normal, documented Windows file. Since could not find any references online and suggested copying the DLL from another machine, treat this as a diagnostic/cleanup task rather than a simple file-replacement job. was right to suggest collecting a startup log first — a startup scanner shows where Windows tries to load the missing DLL, which is the crucial clue.

Suggested diagnostic steps (in order):

  1. Boot Safe Mode and search the registry for the string rvnpknwp.dll (RegEdit -> Edit -> Find). Check the common startup locations:
    HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
    HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
    %ALLUSERSPROFILE%\Start Menu\Programs\Startup and the per-user Startup folder.

  2. Use a dedicated startup viewer (Autoruns or an equivalent) to locate any reference and note the full image path or service name. If the DLL is registered as a service, inspect HKLM\SYSTEM\CurrentControlSet\Services for entries that reference it.

  3. If an entry is found, export the registry key or create a restore point before removing the value. Removing the startup reference avoids the startup error; do not copy DLLs into System32 from unknown sources.

  4. Run sfc /scannow to restore legitimate Windows files (it will not restore third-party DLLs). Follow with full scans from up-to-date AV and a second-opinion on-demand scanner.

Cautions: never copy random DLLs from another PC unless the exact same OS build and architecture are confirmed; editing the registry and deleting services can break a system if done without backups. If a full diagnosis is needed, supplying an Autoruns or HijackThis-style startup log plus OS and architecture will let experienced responders point to the offending key.

I have no idea what that is lol, but if that doesn't work, you could try hooking that HDD up to a different computer and copying the file over from a different computer running the same OS and service pack (or equivalent). Just be careful plugging a HD into a separate computer, as I hear it can cause data corruption if you don't configure it right or something.
