Armen,
Here is my guess as to what happened:
1. You had Netscape installed on your machine.
2. You installed the LabVIEW Run-time Engine which installed the remote panel plugin into Netscape.
3. You uninstalled Netscape.
4. You are trying to uninstall the LabVIEW Run-time Engine.
If this is correct, then try installing Netscape again, uninstall the LabVIEW Run-time Engine, and finally uninstall Netscape again. If this does not work, then please submit a phone request at http://www.ni.com/ask to get help with MSIBlast.
