Moving to Photoshop forum.
Did VueScan install a plugin for Photoshop 7?
Is VueScan using the TWAIN or WIA interfaces?
Have you tried Photoshop CC 32 bit? (which will work with older plugins and drivers that are 32 bit only)
Thank you for your response. Don't know exactly what the Vuescan installation did other than install a Vuescan driver for the scanner. Photoshop 7 shows the file/import entries: PDF Image..., Vuescan, SE A3 USB 1200 Pro..., SE A3 USB 1200 Pro_Network..., Nikon Scan 4.0..., Vuescan TWAIN..., WIA-ScanExpess A3 USB 600/1200 P..., and WIA Support.... Photoshop CC shows the entries: Frames to Layers..., Vuescan, and WIA Support.... I don't know how to interpret all these entries.
I take it that I could be running a 32 bit version of Photoshop CC instead of a 64 bit version, and that that might render the scanner visible. How does one download the 32 bit version? What practical disadvantages, if any, would there be in running a 32 bit version in preference to the 64 bit version?
Are you the Chris Cox who plays 'cello?
Nope, no cello.
Sounds like the old Nikon code was using TWAIN (32 bit) in Photoshop 7.
TWAIN will still work in Photoshop CC if you install the optional TWAIN plugin, and run 32 bit (because TWAIN on Windows doesn't seem to have 64 bit support).
The 32 bit version of Photoshop CC is already installed -- we install both 32 and 64 bit versions.
Older plugins and drivers that don't have 64 bit code can still work with the 32 bit app.
I played string quartets with a guy named Chris Cox roughly 40 years ago.
Yes, I see that both versions of Photoshop CC have been installed. I have downloaded the TWAIN plugin for Photoshop and copied it into the appropriate X86 folder. The file/import menu for Photoshop CC (32 bit) now looks identical to the file/import menu for Photoshop 7.
I think you have solved my problem. Many thanks. (To you also, Garth.)
I know lots of Chris Cox's, but none of them play cello that I know of.
Glad to hear you have it working.
