We are becoming increasingly frustrated at the failure of Adobe to provide Twain (scanner) support for 64bit Photoshop, or to provide any schedule for this to be implemented, or even apology for the omission It is ridiculous that customers are forced to open a separate software to scan into Photoshop.

Adrian, are you referring to Windows or Mac?

Shouldn’t this be directed at the scanner manufacturer who hasn’t updated their TWAIN drivers to 64-bit?

Andrew,

I know you're a Mac guy, so on the Mac side, yes. On the Windows side, TWAIN isn't supported at all in 64-bit as things are moving towards WIA which is less flaky than TWAIN.

Here's our knowledge base document on TWAIN:

TWAIN plug-in | Photoshop CS4, CS5: http://adobe.ly/PS-TWAIN

Personally, I do all my scanning in the background with the stand-alone scanner software. All TWAIN really does is call that software, so there’s no quality difference, plus you’re not locking Photoshop up (a $700) just to doing scanning (that the free software that came with the software is fully capable of). That way you can retouch and edit images in Photoshop while you scan in the background – which I find is far more efficient.

I kind of figured on Windows there’s no support at all so I’m not sure complaining to Adobe will help (is there anything you could do anyway?).

We can't do anything about TWAIN 64 bit support on Windows until Microsoft or a scanner maker makes the TWAIN DSM 64 bit and provides a working driver to test against.

---> I recently read the following on a blog, & wondered if it was true, but I couldn't find the Twain plugin they refer to. If such a plugin exits, please tell me how to obtain it, as I'm really dependent on the Twain Import capability I had on an earlier version of Photoshop:
My scanner: CanoScan 8600F
------------------------------------------------------------------------------------------------
Blog Entry: CS4 Scanning Fix!!! - TWAIN Scanner's Don't show Up!
________________________________________
Ok, so I have a CanoScan LiDE80 and LiDE100.

When I got CS4, and installed it, neither of those would show up under the File>Import menu. Normally they'd be there, you'd click them, and it launches the scangear app within photoshop.

Basically they were MIA.
I found a folder on the installation DVD called "Goodies"
In there is a folder called Optional "Plug-Ins"
In there is a folder called "Import-Export"

What is the ONE file in that folder??? TWAIN.plugin

Put that into Adobe Photoshop CS4/Plug-ins/Import-Export and you are golden. This should work for any TWAIN-based scanner. I can NOT believe Adobe didn't include this in the basic install of Photoshop, as it's been there at least since CS, probably since before that, and MOST scanners are still using TWAIN.

I hope this helps someone!

Crashes in third party TWAIN drivers are a constant source of complaints and tech support calls. Because we can't control or fix those third party drivers, we had to make the TWAIN driver an optional install. And as noted above, there is no 64 bit TWAIN on Windows, only 32 bit.

Thanks Chris --

I would be happy to use WIA, & do for most tasks, but the problem with it is that the max resolution I can dial up is 600 dpi, while the CanoScan 8600F goes up to 4800x9600.

Since Adobe's products are so prominent, I hope someone comes up with a STANDARD, universal driver, because when a product used by many thousands of customers loses a certain capability, the multiple that's applicable to productivity loss can be incredible.

I think the question is why doesn't Canon create a WIA interface just like their ScanGear TWAIN interface.

The Question is, why Adobe Photoshop Elements not start the 32Bit Twain in a 32-Bit-Modus. Win 7 supported 32 Bit.

Where's the Problem?

That sounds like it belongs in a different topic on how to install the optional TWAIN plugin for Elements. (and it is optional because too many scanner drivers crash when you simply ask for their name)

On my PSE 8 the TWAIN Interface not crashed.
It should provide a 64 to 32 Bit interface for Use the Old TWAIN Interface from older versions fo Photoshop elements, for exempfe PSe 12.

I have try to see, take PSE 12 and not PSE 13. PSE 12 is not availaible. I have an Download of the PSE 12 not found.
