Installation via GUI is like 2 clicks after accepting license agreement. Works splendidly.

However, I have many systems I need to install the UF on, like a few hundred. I even turned on the verbosity of the install, and this is all I get: === Verbose logging started: 6/14/2018 12:11:21 Build type: SHIP UNICODE 5.00.7601.00 Calling process: C:\Windows\system32\msiexec.exe === MSI (c) (B4:68) [12:11:21:286]: Resetting cached policy values MSI (c) (B4:68) [12:11:21:286]: Machine policy value 'Debug' is 0 MSI (c) (B4:68) [12:11:21:286]: ******* RunEngine: ******* Product: splunkforwarder-7.1.1-8f0ead9ec3db-x64-release ******* Action: ******* CommandLine: ********** MSI (c) (B4:68) [12:11:21:286]: Client-side and UI is none or basic: Running entire install on the server.
