The WIA and TWAIN plugins for Photoshop are intended for more casual use, and may be preferable to the expense and overhead of a separate application. But even if it did, and you installed a 64-bit DSM, the second problem is that there are virtually no 64-bit compatible TWAIN scanner drivers (data sources) available from scanner manufacturers (it's a classic chicken & egg problem-there's litte demand for 64-bit data sources, so there are very few 64-bit data sources.)ĭedicated scanning applications like VueScan are popular among people who have more demanding needs for controlling the scanning process, or do a large volume of scanning.
While it is possible for more technically experienced users to download and install a 64-bit compatible DSM to replace the Microsoft version (see ), there are two problems: first, the Photoshop TWAIN plugin is 32-bit only, and will not work in the 64-bit version of Photoshop regardless. There is no 64-bit TWAIN support in Photoshop on Windows primarily because the TWAIN data source manager (DSM) that Microsoft ships with Windows is 32-bit only. You will need to run the 32-bit version of Photoshop to use your scanner. You will also need to install TWAIN drivers for your scanner by getting the appropriate software from the manufacturer's web site or installation disk. You can download the TWAIN plugin from, and install it in the 32-bit version of Photoshop. The TWAIN support in Photoshop CS6 for Windows is exactly the same as it was in CS5 and earlier. I am relatively new to Win 7 but in older versions you had the ability to change icons, can this be done, or would this need a maintenance release of CS6 32 bit
PS: I would like to pin the 32 bit version onto my tool bar, but the 32 bit and 64 bit share the same Icon which makes it confusing - could just be me. I have a whole bunch of 4x5 negatives to scan, so that should be a good testīy the way, my scanner is the Epson V700. Will go on to do some more testing, and let me know if anyone is interested in the results. Adobe engineers swore blind the problem was with Epson and that was the root cause of File/Automate crashing. Interesting that File/Automate works just fine with the plugin installed. Also check also your OS, if your using windows, ensure that your OS is in 32-bit-mode because Twain will not work in Photoshop if its running 64-bit-mode. There is a weird GUI bug that prevents the Epson Scan Window appearing in Photoshop but can live with that. for installing Adobe Photoshop Twain plugin for CS6, make sure that you are installing twain plugin for Photoshop CS6 and not from Photoshop CS5 downloads. Well I have installed the plugin for Photoshop CS6 (32 bit) and the Windows 7 (64) bit driver from Epson and it works and made my first scan.
