I am (well, I actually was) using 64-bit LO v. 5.3.7 on my home PC, with Windows 7 Pro.
Yesterday, I tried to acquire an image into Writer but the Select Source window was empty and no scan was possible.
I’ve got two scanners installed on my system: a “several-years-old” flatbed Epson Perfection 3270 and the one embedded in the Lexmark MX317DN Multi-Function laser printer, which i just bought a couple weeks ago: apparently none of them can be used with Writer.
After some investigation, I remembered an issue I had several months ago with a popular graphics software (Corel Paint Shop Pro): it was 64-bit, too, and claimed to be impossible to use 32-bit TWAIN drivers. Solution: use the 32-bit version of the applicaton.
So, I tried installing the 32-bit LibreOffice and voila, both the scanners are now working.
I wonder if there can be a way, for 64-bit LO, to use 32-bit TWAIN/WIA scanner drivers, since hardware vendors do not appear so much 64-bit-oriented.
As I said, I’ve recently bought a new multifunction printer and it just came with 32-bit drivers.
Of course, the vendor claims it’s “compatible with 64-bit OS”… not a word about “64-bit applications”.
