Canons are great. The 9000F I mentioned is awesome. If you go beyond document and photo scanning and want to also scan things like slides and negatives, or achieve the highest possible resolution, it's the flatbed scanner of choice. Great for large photo scans (8x10's, 8x12s).
The LiDE series on the other hand is a basic home consumer series .. and it too does a great job with documents and family photos. If you mostly do documents and occassionally a snapshot or two, the LiDE 100 is fine. It has a resolution of 2400x4800 max. If you can spare the extra $30, go for the LiDE 200. It has a top resolution of 4800x4800. You will get better photo scans.
On the attempt to install the Visioneer, your system scanned for the hardware change and identifies a "42-bit USB scanner" ... correct?
And then you scanned for an updated driver and it found none? Did you check to allow your computer to look online? Did you check the c:\windows\system32 folder?
Just want to make sure on this (I'm an IT consultant BTW).
Here's another set of instructions to try if you choose...
1) ---removed - not relevant ---
2) Download the driver executable
3) On your local machine, whereever you downloaded the file to, right click on 4400.303110.EN.exe and select properties
4) Select compatibility tab
5) Select the run this program in compatibility mode for Windows XP (Service Pack 2)
6) Privilege Level select the box "Run as Administrator"
7) Select OK or Apply. You MUST set compatibility before you install the driver pack.
8) Run the 4400.303110.EN.exe and install the driver
I saw a pop up on the screen about some missing twain.dll error. I just dismissed it.
9) Plug in scanner and driver should load correctly.
10) Go to Start -> All programs-> Windows fax and scan application and test it out.
This is know to work with Vista (which also didn't have a driver) and Vista is much more finicky than Win 7 is. So it could work
