In KB44781 there is a link to download the uninstaller file named UninstallPulseComponents_V2. The URL for the link is https://corpfiles.pulsesecure.net/share/MnxXRDl4xYsQ@@@QrPLIQYlg==p?dn=1.
That corpfiles site isn't responding for us from several differerent locations (different Internet connections - home, office, etc). Anyone having luck getting to this web site?
Works for me
