after uninstalling, restart your computer. then start windows explorer and see if there is still a folder with the name of the software under c:program files. be sure to check the registry as well for remnants of quartus. to do this, start regedit, then look under hkey_local_machine > software for quartus or the name of the producer. always keep in mind that only a computer professional should ever directly delete entries in the windows registry.
