Solution

If the "LabVIEW" feature is not installing, it could be due to either an MD5 mismatch or a patch has already been downloaded.

• MD5 mismatch: If the MD5 Hash of the downloaded installer does not match the MD5 on the download page, the downloaded installer is likely corrupted. 
  1. Check the MD5 checksum of a downloaded file (third party link)
  2. After checking the MD5 of the downloaded file, compare that value to the Checksum (MD5) on the download page:

3. If the MD5's don't match, re-download the installer and try again. If both MD5's match, check the previously downloaded LabVIEW versions .

• Upgrade has already been downloaded: For example, if you had already downloaded LabVIEW 2017 SP1 and then try to download LabVIEW 2017, the LabVIEW 2017 feature will not be installed since SP1 is built upon the base version, which is 2017. 
  1. To be able to install the base version (i.e. LabVIEW 2017), you will first need to uninstall the patched version (i.e. LabVIEW 2017 SP1)
  2. After it is uninstalled, you can now install the base version (LabVIEW 2017)
• Licensing Mismatch: If LabVIEW identifies that an upgrade will make your licensing invalid (for example upgrading to 2019 on a 2018 license), it will refuse to make the update.
  1. Make sure you have the proper licenses installed
  2. If you are using a volume license server and have recently upgraded, you may have to refresh your license server by re-adding it to NI License Manager.
