Solution
This issue is often caused by your computer being unable to successfully contact NI.com to download files needed for the installation.
If you encounter this issue on a computer with NIPM already installed, then one approach is to
uninstall and
reinstall NI Package Manager. This is best done after temporarily disconnecting your computer from the network or web, which should stop the hanging behavior when NI Package Manager tries to launch during the uninstall process. Once NI Package Manager is reinstalled, you should be able to install your other NI software from the application.
If you do not have NIPM installed already, then an alternative approach is to use either physical media or the offline installer. The offline installer can be found on any NI software download page by selecting the
Individual Offline Installers link beneath the typical, online
Download option.
