What are PCCompanion.dll Error Messages?


Dynamic Link Library PCCompanion.dll Errors

PCCompanion.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like PCCompanion.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. Sony PC Companion) could share the same PCCompanion.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 PCCompanion.dll is attempted to be loaded either when Sony PC Companion is starting up, or in some cases already running. Some of the most common PCCompanion.dll errors include:

Your PCCompanion.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Sony PC Companion), or deleted by a malware infection. Furthermore, PCCompanion.dll file corruption could be caused from a power outage when loading Sony PC Companion, system crash while loading PCCompanion.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 PCCompanion.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 PCCompanion.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

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many PCCompanion.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  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 PCCompanion.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your PCCompanion.dll File (Caution: Advanced)

Download PCCompanion.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying PCCompanion.dll to your appropriate Windows system directory. Sony Mobile Communications typically does not release Sony PC Companion DLL files for download because they are bundled together inside of a software installer.
