I don't use my scanner often (Windows 7 Pro, so supported), but tried to use it the other day and it says the twain driver is missing.
Tried reloading software/drivers (current) and the twain driver. No help. I don't think the twain driver is reloading, it just runs and then is gone.
I've tried the delete driver utility and reload, still no help.
What else can I do?
