What are SyncML.dll Error Messages?

Dynamic Link Library SyncML.dll Errors

SyncML.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like SyncML.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 SyncML.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 SyncML.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 SyncML.dll errors include:

Access Violation at address - SyncML.dll.
SyncML.dll could not be found.
Cannot find C:\Program Files (x86)\Sony\Sony PC Companion\SyncML.dll.
Cannot register SyncML.dll.
Cannot start Sony PC Companion. A required component is missing: SyncML.dll. Please install Sony PC Companion again.
Failed to load SyncML.dll.
The application has failed to start because SyncML.dll was not found.
The file SyncML.dll is missing or corrupt.
This application failed to start because SyncML.dll was not found. Re-installing the application may fix this problem.

Your SyncML.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, SyncML.dll file corruption could be caused from a power outage when loading Sony PC Companion, system crash while loading SyncML.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 SyncML.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 SyncML.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):

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

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

Step 2: If recently installed Sony PC Companion (or related software), uninstall then try reinstalling Sony PC Companion software.

You can uninstall Sony PC Companion software by following these instructions (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "Uninstall" and press "ENTER".
In the search results, find and click "Add or Remove Programs"

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 SyncML.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

If Windows Update failed to resolve the SyncML.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 SyncML.dll File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate SyncML.dll file version. We maintain a comprehensive database of 100% malware-free SyncML.dll files for every applicable version of Sony PC Companion. Please follow the steps below to download and properly replace you file:

Windows 10: C:\Program Files (x86)\Sony\Sony PC Companion\
Windows 10: C:\Program Files (x86)\Sony Ericsson\Sony Ericsson PC Suite\
Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.

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

CAUTION : We strongly advise against downloading and copying SyncML.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.
