Attempted to install according to documentation and results are inconsistent. SmartView for MS installs totally fine on most machines, but on a select few, fails without any feedback. Download, unzip, launch installer with and without admin rights. If any MS apps are running we get the prompt to close them, then to select an install destination, leave it default, click OK and that's it. Cursors spins for a moment and then the process fails without any error or feedback otherwise. Testing failure on a brand new laptop to exclude older version conflicts etc. Machines from both pass and fail groups on the same network, firewall, AV, updated Office versions, Windows patching, etc. All like that I can find. Very stuck, hearing any and all suggestions. Thanks.
