Additional Information
This is because each SP1 release is a major release of LabVIEW and is independent of the non-SP1 release, meaning it's not necessary to install the non-SP1 release first.
Also, if you have a license for the non-SP1 LabVIEW release, it will not necessarily activate the LabVIEW SP1 release unless you have an active
SSP membership.
