This can be a controversial topic as some people use such tools to beat copy protection (Mount a virtual copy of a CD so a program thinks the required CD is mounted in the drive or make ISO images for other purposes).I've heard rumors that games such as Doom3 won't even run if such tools are found installed. From the Daemon Tools site: "This page only supplies information and tools necessary to make a PERSONAL BACKUP of legally owned CDs.

It's a question of software and of the way it is conceived. I have the same problem with some of my dictionaries. Give me an example: is it a dictionary? Which dictionary? I also don't know how to solve this kind of problem. Perhaps someone here will give you a more detailed answer.
