JuniperSetupClientInstaller.exe identifies itself as 8.1.4.60331 created 2/16/2016 and when I try running it from Firefox it crashes with a "failed to download" error. Saving to the local drive and running it shows "completed" immediately without installing, and then it doesn't work on the vpn page it is supposed to since that fails to detect the load but wants to download it all over again. Uninstalling all Pulse Secure software and trying again goes through a quick unpacking of components, but then the result is still the "completed" window that doesn't work. On one try the data execution prevention was activated, so I turned that off for this file but that still doesn't make this install work on Vista 64-bit home premium. Firefox and Java are the latest, updated multiple times. Cleared cache, rebooted, but that doesn't work. Run as administrator doesn't work either. This started to fail by Fall of 2015 and local IS was not able to fix it but simply recommended a Windows 7 or newer computer. Before this failed, prior versions have worked on this computer for many years.
