TWAIN is an interface used to import from imaging devices, such as scanners. For more information, see the TWAIN Working Group's website at www.twain.org. The Photoshop TWAIN plug-in connects with compatible devices that are installed on your computer.

When a 32-bit TWAIN aware application scans using a WIA driver on a 64-bit Windows Vista or Windows 7 system, the TWAIN application may stop responding. Cause If you leave the scan dialog open for about ten minutes before you push the Scan button, the message used to transfer the scanned image from the WIA driver to the TWAIN application is. Twain scanner works fine on 32-bit but not on 64-bit. Data source files. So 32 bit apps will load only 32 bit DS files and same applies for the 64 bit apps. The twain spec provides a very elaborate discussion on this. Install-Package asprise-scan-scanner-twain-wia-api. Here is the documentation to C# VB.NET Twain Scanning Library API.
The TWAIN Plug-in provided on this page is NOT compatible with Photoshop CC 2015.5 and later on Mac OS.
Due to limitations with TWAIN in Photoshop, we strongly suggest the following alternatives for scanning your images:
Use the stand-alone scanning software included with your scanner
Most scanners provide a stand-alone scanning application that can be used to scan and save images.
Using the stand-alone scanner software avoids issues associated with TWAIN. Using a dedicated application to scan allows you to retouch and edit images in Photoshop while you scan in the background – which can be more efficient.
If you use a stand-alone scanning application, save your scanned images as TIFF files, then open them into Photoshop.

Some scanner software lets you designate Photoshop as the external editor for an image after a scanning is completed. Consult the documentation that came with your scanner or contact your scanner manufacturer for more details.
Mac OS:
Use Apple’s ImageKit technology instead of TWAIN to scan directly into Photoshop. Support for ImageKit is built in to Photoshop without requiring a plug-in, and provides access to many scanners.
Instructions: Scan and import images using Apple’s ImageKit interface (macOS only)
Windows:
Use the WIA (Windows Image Acquisition) interface for your device, if it’s available, to scan directly into Photoshop.

TWAIN is not supported in Photoshop when it’s run in 64-bit mode.

When you use TWAIN to import from an imaging device, you may encounter these issues:
- Photoshop or your scanner application freezes or quits unexpectedly.
- You are unable to close the scanner window.
- You encounter errors during import.
- The preview of the imported image, or the imported image itself, appears incorrect onscreen.
Try the following solutions:
Download the latest scanner driver from your scanner manufacturer’s website and install the driver. Be sure to confirm the driver is compatible with the version of the Operating System on your computer.
Use a dedicated third-party scanning application
If your scanner manufacturer doesn't provide updated drivers that are compatible with current operating systems you may need to look at third-party scanning solutions. These third-party utilities are dedicated scanning solutions, and they are more appropriate for critical or high-volume scanning.
Third-party scanning utilities:
If you use a third-party scanning application, save your scanned images as TIFF files, then open them into Photoshop.

Twain Driver 64 Bit Scanner
Juriidilised märkused | Privaatsuspõhimõtted veebis
Active3 years, 1 month ago
I am working on an application(Java Applet) that interacts with scanner. I understand I need a Twain library or WIA library to make it work in windows. But I am not sure what are the differences of two? I am trying to use this library:
JAR file link is broken so I got it from here.http://rsbweb.nih.gov/ij/plugins/twain-scan.html
And DLLs from here: http://sourceforge.net/projects/twain-dsm/?source=dlp
But, it does not detect the source. Here is the error log:
I am on 64bit machine. Anybody had any success?
TWAIN specification is too long to follow and I haven't found any resources on WIA implementation.
Any help/pointers/resources is greatly appreciated.

For twain device control in java, all components need to be in the same mode. i.e. the JRE, Twain DSM (Source Manager), and the Twain driver (Scanner driver) all need to be 32-bit or all 64-bit. No mixing.
The default installation of 64-bit Windows contains the 32-bit mode of Twain DSM. And you say you've downloaded the 64-bit DSM. It's likely that the scanner's driver is 32-bit and that is why it cannot be found.
You have 2 options:
Keep it all 64-bit.
- Use the 64-bit TWAINDSM.DLL.
- Make sure your JRE/JDK is 64-bit.
- Make sure your scanner has a 64-bit driver.
My scanner doesn't have a 64-bit driver available, but I tested a 64-bit configuration using a 64-bit 'virtual scanner' and it worked.
Keep it all 32-bit (recommended)
- Use the 32-bit TWAINDSM.DLL.
- Make sure your JRE/JDK is 32-bit.
- Use the scanner's 32-bit driver (probably default).
You can download 32 and 64 bit twain virtual scanners here.
Note: I mention the JDK because if you're running the code from an IDE it may be pointing to a different JRE to to the system default. True story, happened to me.
