No Scanning Directly into Photoshop CS4 64-bit

Saturday January 17, 2009
The other day I was working on a project in Photoshop and wanted to scan something. I looked in the usual File menu for the Acquire command, but it was nowhere to be found. I did some searching later and discovered a thread on the Adobe Forums explaining that a TWAIN driver is not installed in the 64-bit version of Photoshop because "there is no TWAIN standard for 64 bit Windows. Photoshop cannot support a standard that does not exist."

When another member pointed out that there is, in fact, an API for TWAIN 64-bit support, the thread was left with a "we'll look into it" from Adobe's rep almost two months ago. This is rather disappointing for such an expensive piece of software, especially one in which scanning in an integral part for many users. In the end, I went to my beloved, free XnView software to do my scanning, and the multi-step process of getting the scanned image into Photoshop.

Note that Photoshop CS4 64-bit version does support scanning via the WIA (Windows Image Acquisition) interface if your scanner is also supported by WIA, but this is often much more limited than scanning with TWAIN.

I wonder what other limitations exist in the 64-bit version of Photoshop CS4. Have you found any?

I have been looking around for software for my Sony 64 bit laptop. Now, after hearing this about scanning problems with Photoshop…maybe I’ll wait just a bit and see how it all comes out.

Have run into the same 64 bit problem with a Nikon film scanner – uses an outsource twain connection – but no 64 bit support – oh vista!

If you purchase CS4 64-bit, it also comes with a 32-bit version. I’ve run into this problem with 64-bit CS4 not recognizing certain things (filters, printer software), but I’ve been able to get around it by running the 32-bit CS4 for scanning and printing, and running the 64-bit CS4 to do everything else. Hopefully that helps!

i agree with you. i installed cs4 elements on my pc but the scanning window is very un stable. for me to scan i need to open it several times. well, i finally scan but its time wasting as the window keeps shutting.

I’m unable to find the goodies folder on my CS4 discs to add the twain for scanning film at any bit size. In CS2 scanning film, making contact sheets and creating Web Galleries was very easy. I think they are available and I want to use them. Help
