I have exactly the above problem with my Canon Lide 500F and I solved it the way you suggested. After starting my computer and connecting the scanner I got the same information that the toolbox wasn't able to open the twain source. The toolbox found the scanner but didn't work.

I have a similar problem as Arlene DeBoer. On my laptop (also Win 7 proff.) it works OK

What else can I do

I have the same problem with my Canon D530. It worked fine with my lap top, I just a new computer with windows 8 (I hate windows 8) on it, and I have to keep restarting the computer to get the scanner to work. I tried what the canon support people told me to do, but that did not work. I changed the path like you said above, but it it still is not working right. If I keep right on scanning it is ok, but if I stop for a while it will no longer work without restarting the computer. I am very frustrated.
