The EPSON scanner software fails to open and displays an error notifying that it 'has stopped working' in Microsoft Windows. How can I resolve this?

RELATES TO:

  • Windows 8, Windows 7, Windows Vista, Windows XP, Windows 2000
  • EPSON Scan, EPSON Event Manager, EPSON scanning software
  • Error upon launching the software and program closes

EXPLANATION:

When running the Epson scanner software it may not load correctly and an error message may be displayed. The error message could be a result of a problem during the software installation or a conflict with other software on your computer.

Uninstall and reinstall the Epson scanning software

Do the following:

  1. Open Start then Control Panel. Next, open Add/Remove Programs (Windows 2000 and XP) or Programs and Features (Windows 8, Windows 7 and Vista), then check the software list and uninstall the following programs if found.

      Epson Scan
      Epson Event Manager
      Scanner Assistant

    To complete the software removal, restart the computer.


  2. When the computer has restarted, reinstall only the scanning software you removed in step 1. You can use either the software CD supplied with your Epson product or a download of the latest versions available on the Epson support website. For All-In-One products, you do not need to reinstall the printer driver.

  3. When you have finished installing the software, restart the computer to complete the software installation.

  4. Make sure that your computer and Epson device are powered on and can communicate with each other, e.g. depending on your product, check the FireWire*, USB or Network cable is connecting your Epson device to the computer; or communication is available for Wireless-capable Epson products.
    (*FireWire is only supported when using Windows 2000 or XP.)

  5. Only one USB scanning device (scanner or All-In-One) can be used at a time within the Windows operating system, so disconnect all other devices apart from the one you are currently using. (This will help during the setup process.)

  6. Check that there are no errors displayed on the front of your Epson device. If there are no errors, attempt to scan using Epson Scan rather than via a third party application. To do this, double-click the EPSON Scan shortcut icon on the Desktop or click Start > Programs > EPSON Scan > EPSON Scan.

If you can preview or scan, the issue is resolved and no further troubleshooting is required.


Further troubleshooting

If the error still appears after reinstalling the software, check if there are any instances of software or files associated with a scanner or All-In-One from a manufacturer other than Epson installed on the computer. If either are present, this may cause a conflict with the Epson device installation.

  1. Open Start then Control Panel. Next, open Add/Remove Programs (Windows 2000 and XP) or Programs and Features (Windows 8, Windows 7 and Vista).

  2. Check the software list for any scanner software belonging to other manufacturers. If software is listed then we recommend uninstalling the software to help identify the cause of the current problem. Contact the manufacturer of your other scanning devices or refer to the manufacturer's documentation for advice on removing the software.

  3. Next, check if any scanner files are installed in the twain_32 folder in Windows.

    1. Open Computer (Windows 2000/XP) / My Computer (Windows 7/Vista) / This PC (Windows 8) or Windows Explorer from either the Desktop or the Start menu.
    2. Locate the local hard drive that the operating system is installed on (usually C:).
    3. Open the local hard drive (usually C:).
    4. Open the Windows folder.
    5. Open the twain_32 folder.
    6. Check the list of files in this location. The file wiatwain.ds is the Windows WIA scanning file and the folder escndv contains the Epson Scan files. Do not remove these files as both are required.

    7. If you see any other folders or files, these should be removed as they are likely to belong to other manufacturers' devices.
      1. Highlight any folders/files that are not named 'wiatwain' and 'escndv' (e.g. a file with the extension '*.ds'), then right-click on a highlighted file and left-click Cut from the menu.
      2. Navigate to the Desktop - you can do this from the active window or by minimising any open windows.
      3. In case you need to restore these files later, copy them to the Windows desktop. To do this, right-click on an empty area of the Desktop and left-click on Paste. The files you removed from 'twain_32' will be copied here; leave the files on the Desktop or move them to an alternative location as preferred as a back-up in case they are required again, in which case they can be moved back to the folder.


  4. Next, try opening the Epson scanning software again. If any (e.g. Epson Scan) open without displaying the error messages detailed above, the issue has been resolved.

    If you removed any software or moved files from the 'twain_32' folder, you have the option of not re-installing the software or installing the software one at a time to identify the software causing the problem with your Epson device.
