When you tried to unistall LabVIEW and ELVIS in your Windows Control Panel, did you make sure to select the National Instruments folder under the list of programs first? Also, do you have any other National Instruments software installed on your computer? If you navigate to the National Instruments folder in Control Panel and still do not see your LabVIEW software, please e-mail or call into support. We will be able to send you a special utility which will remove your software even if it doesn't show up in Control Panel. It sounds like this issue would be fixed by a reinstallation. Thanks!
