From Adobe.com... should help:
+To run Photoshop CS5 on Mac OS as a 32-bit application:+
+Select the Adobe Photoshop CS5 application file, installed by default in the Applications/Adobe Photoshop CS5 folder.+
+Choose File > Get Info, and select Open in 32 Bit Mode.+
+Deselect this option to run Photoshop CS5 in 64-bit mode.+
Guess the Canon drivers are not 64bit compatible.
I don't remember how many versions of Photoshop it goes back but you haven't been able to scan directly from/into Photoshop for years (like we once did). I use an Epson scanner and use their software, or Hamrick's VueScan, to scan and then open in Photoshop CS5. Another responder is correct, some plugins don't work if you open CS5 in 64-bit mode, in my experience, Alien Skin's plug-ins.

Yup, not even the latest version 6 of Alien Skin's Eye Candy. They are working on a free 64 bit update to it, just no word yet on when it will be ready. OnOne Software's Mask Pro 4 was just released as version 4.1.8, which is supposed to work in 64 bit mode, but doesn't. I and a few others have noted it in their forums. No response yet.
Has anyone found a resolution for this?
I have a CanoScan 8600F, that come **** or high water, I cannot get Photoshop CS5 to see. Have read & watched, tried everything suggested, etc.. I do not want to have to throw more money after another application, such as VueScan.
Anyone? Anyone at all? Anything?
Actually, I've never understood why people want to use this workflow. The only advantage to it is that you don't have to save the scan to the hard drive first, and then open it from there.
But what about PS itself? If it crashes for any reason before you've saved your image, you have to scan it again. Good scanning software should also be able to let you queue as many images to scan as you can get on the glass. After the first one finishes and is saved to disk, open that and work on it while the scanner continues on with the rest.
CS5 no longer supports TWAIN drivers period. I use vuescan others use silverfast, the quality is far superior and allows you to keep working in PS while you scan. Plus it allows you to calibrate your input/output using IT8 cards, it even makes printer profiles. My color control has been perfect since purchasing, plus its fast, I'm very impressed.
I understand cost issues but, the benefits in productivity will far out weigh doubt and besides any worthy client deserves the absolute best.
If anyone decides to got this route, avoid the kodak Q60 cards. Their expensive,mass produced and therefore untrustworthy.
I recommend Wolf Faust for the absolute best German engineered IT8 system.

Thank you very much for that link, pixelsurery. The Kodak targets are what I've used, but have never been real happy with the profiles they produce. I knew from the start they weren't very accurate, but couldn't find a suitable replacement. I will definitely be purchasing one of the Wolf Faust targets. Both reflective and transmissive.
TWAIN scanner drivers are still supported in Photoshop CS5, but the TWAIN support plugin is no longer installed by default.
You need to do the following:
• Go to the Adobe website. In the Download section, look for Photoshop CS5 updates.
• Download the "Photoshop CS5 12 Optional plugins" file for your language version of Photoshop.
• Once the download is complete, double-click the "CS5Optional_PlugInsInstaller.dmg" file.
• Double-click the file "CS5 Optional Plug-Ins.mxp". The Adobe Extensions Manager will launch and the install process will start.
• When it is finished, quit the Adobe Extensions manager.
• Launch Photoshop CS5.
If the scanner driver is still not visible in the Import menu, your scanner driver may not be 64bit compatible. In this case:
• Right-click on the Photoshop CS5 application icon and select "Get Info".
• In the information window, check the box that says "Run in 32 bit mode".
This solved the scanner problem for me.
