What are icudt57.dll Error Messages?


Dynamic Link Library icudt57.dll Errors

icudt57.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like icudt57.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like replace.exe - to follow. These files were created so that multiple programs (eg. WampServer) could share the same icudt57.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 icudt57.dll is attempted to be loaded either when WampServer is starting up, or in some cases already running. Some of the most common icudt57.dll errors include:

Your icudt57.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with WampServer), or deleted by a malware infection. Furthermore, icudt57.dll file corruption could be caused from a power outage when loading WampServer, system crash while loading icudt57.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 icudt57.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 icudt57.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 icudt57.dll error, please proceed to the Step 2 below.

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

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

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for WampServer 3.1.9 and click "Uninstall"
  5. Follow the prompts for uninstallation.

After the software has been fully uninstalled, restart your PC and reinstall WampServer software.

If this Step 2 fails as well, please proceed to the Step 3 below.

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 icudt57.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  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 icudt57.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 icudt57.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 icudt57.dll file version. We maintain a comprehensive database of 100% malware-free icudt57.dll files for every applicable version of WampServer. Please follow the steps below to download and properly replace you file:

  1. Locate your Windows operating system version in the list of below "Download icudt57.dll Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate WampServer folder location:
    Windows 10: C:\wamp64\bin\php\php7.0.33\
    Windows 10: C:\wamp64\bin\php\php7.1.29\
    Windows 10: C:\wamp\bin\php\php5.6.40\
    Windows 10: C:\wamp64\bin\php\php5.6.40\
    Windows 10: C:\xampp\apache\bin\
    Show 2 more directories +
    Windows 10: C:\xampp\php\
    Windows 10: C:\xampp\php\windowsXamppPhp\
  4. 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.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve icudt57.dll problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.



Download icudt57.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying icudt57.dll to your appropriate Windows system directory. Romain Bourdon typically does not release WampServer DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing icudt57.dll and all other DLL files for WampServer. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
