I have vista. I was trying to install nero 9. But the setup failed in between. But the temporary files that the setup extracted are still there on my system. They are taking space of around 1 GB.( I saw disk usage before and after the installation). How to remove those files?(means what is the location) I have already deleted the folder "Nero" it created inside Program Files. But I am sure that temoporary files are still there. Also how to remove the entry from installed programs in Control Panel.
Use the official Nero General Clean Tool:
