error during installation

[alexifera]

When I try to install daemon tools 3.47 on the screen appears this error: "Some driver has invalid name or conflicts with other files or service in system. Please choose other driver names or make sure you have rebooted after removal of software using same names."

What can I do?
When I've tried to install daemon tools for the first time, the system crash when the installation wasn't complete. After that everytime I try to install d-tools appears this error.

Check thread about error 25002 in common problems and solutions forum.
Also check if you've e.g. Starforce protected games installed.
Which OS do you use? Any reason why you still use v3.47?
