A powerful virtual disk mounting software utility, Daemon Tools allows loading a disk image on your hard drive cache. The Daemon Tools software suite contains an uninstall file that removes most related files from your system. Generally, uninstallers such as those equipped with Daemon do not remove the registry entries that were created during the installation process. If you have decided to permanently remove the Daemon Tools software from your computer or you are having difficulty reinstalling, you can manually delete the registry information using the Windows Registry Editor.
Press the "Windows" and "R" keys simultaneously on your keyboard. This opens a Run box.
Type "Regedit" into your Run box and press the "Enter" key. This loads the Windows Registry Editor.
Navigate to "HKEY_CURRENT_USER\Software\DT Soft" in the left pane.
Right-click the "DT Soft" folder in the left pane and then click "Delete." Click "OK" on the confirmation dialogue and close the Registry Editor.
