Windows 7 Ultimate x64
My WIA Driver solution for Win7 x64, hope it helps you, too.

I got tired of this wia driver problem with Windows 7, specially for x64. Just to share, this is how I solved my problem.

I have a Canoscan LiDE25, and of course, encountered the same problem with you even though we have downloaded the so called x64-bit drivers from the manufacturer of our product. Yes the driver is there, however, the functionality of the scanner is gone as well.

To solve:
1. Install again (or if you have another computer) on a computer with Windows XP the drivers and the software for the scanner, xp 32-bit version of course.
2. Go to folder windows and copy the twain_32 folder (on a USB, or any other portable devices from which you can transfer the files to the computer witn Windows 7 64-bit. For my part, for LiDE25 twain_32 folder contains two folders (CNQL25 and CNQSG plus a file named wiatwain.ds
3. Install the 64-bit driver (this is for the registry purposes only) on your windows 7 64-bit.
4. Now copy twain_32 folder (from winXP) into windows (of Windows 7, of course) and overwrite the whole of twain_32 folder.
5. For my scanner, i made a shortcut of the file SGST.exe (this is scangear, from the folder CNQSG) on to my desktop if I just have to use the scanner by itself.
6. Presto! It works! And all my other software now that needs to make a scan (CorelDRAW X5, AbbyFineReader, MSOffice, Adobe) can make a scan through their own context menu and can trigger and run scangear as if you are working with it from windows xp. No errors or whatsoever.

Note: tried and tested this procedure several times, thinking it might be a fluke. but it always work everytime. I hope this procedure will also work with other hardwares that always get the error "you need a WIA driver to use this..."

Now I can finally stay with Windows 7 64-bit (this is the only problem holding me from migrating to windows 7 64-bit)
