What are ARKCmdDefrag.dll Error Messages?


Dynamic Link Library ARKCmdDefrag.dll Errors

ARKCmdDefrag.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ARKCmdDefrag.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Adobe Photoshop Lightroom) could share the same ARKCmdDefrag.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when ARKCmdDefrag.dll is attempted to be loaded either when Adobe Photoshop Lightroom is starting up, or in some cases already running. Some of the most common ARKCmdDefrag.dll errors include:

Your ARKCmdDefrag.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Adobe Photoshop Lightroom), or deleted by a malware infection. Furthermore, ARKCmdDefrag.dll file corruption could be caused from a power outage when loading Adobe Photoshop Lightroom, system crash while loading ARKCmdDefrag.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix ARKCmdDefrag.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your ARKCmdDefrag.dll issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the ARKCmdDefrag.dll error, please proceed to the Step 2 below.

Step 2: If recently installed Adobe Photoshop Lightroom (or related software), uninstall then try reinstalling Adobe Photoshop Lightroom software.

  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the ARKCmdDefrag.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.
