RELATES TO:

• 64-bit versions of Microsoft Windows (Windows XP x64, Windows Vista x64, Windows 7 x64).
• Adobe Photoshop CS4.
• Scanning functionality - importing to Photoshop.
• Epson Scanner & All-In-One ranges.

EXPLANATION:

Adobe Photoshop CS4 requires a TWAIN plug-in to recognise your scanner and for you to be able to select your scanner from the File > Import menu. 32-bit editions of Photoshop CS4 install this plug-in by default, but 64-bit editions require a 64-bit version of this plug-in. Neither Adobe or Microsoft immediately released this plug-in after the release of CS4.

For more information and to check for updates, please refer to Adobe Knowledgebase article on Adobe's website, kb405072.

• For enquiries or support regarding CS4, please contact Adobe Systems Inc.
• Click here to visit the Microsoft Support website.

Epson provides third-party contact information to help you find technical support. This contact information may change without notice.

Until a 64-bit plugin is released, you can try the following workaround options to scan into 64-bit editions of CS4:

• Use Epson Scan to scan and save your images to your hard drive, and then open them in Adobe Photoshop CS4 (64-bit). The majority of Epson scanners and All-In-Ones have a 64-bit Epson Scan driver to enable you to install and use your Epson device in Windows Vista x64 (64-bit). Epson Scan is included on the software CD and is available via the Drivers & Support section of your website.
  

  We recommend saving your images as TIFF files since they offer better compatibility and TIFF is a lossless (data is not lost) file format. See the following article for help: How to perform a basic scan with EPSON Scan.

  
  
• Use the Windows Image Acquisition (WIA) from the File > Import menu to import images from the scanner.
  
  

  Note:
  The WIA driver does not offer all the features and control provided by the Epson Scan driver. It also does not support scanner options such as a Transparency Unit (TPU) for film scanning or an Auto Document Feeder.

  
  
• Use Photoshop CS4 (32-bit) to scan using the File > Import menu. You can then save the file and re-open it in Photoshop CS4 (64-bit).
  
  

  Note:
  Both a standard 32-bit version and a 64-bit version of CS4 are installed by default when you install Adobe Photoshop CS4 on a Windows 64-bit operating system. (You can override this default setting when you install the program.)
