So if it wasn't clear, this release had issues. It wasn't intended to be the final LabVIEW 2018 SP1 and was an version between SP0 and SP1 for testing. It was unintentionally released to the public and wasn't intended for the general public to use, and likely won't activate. The release was pulled and if you did download it you are better off not using it until the actual SP1 release. On top of not being intended for an actual release, and not activating, it also has a bug with upgrading from 2018 f2 to 2018 SP1 which is being addressed for the actual SP1 release.
