How to install a Windows universal forwarder via command line?

[DPWSplunkPOC]

I want to install the windows universal forwarder via command line.

My command is:

msiexec.exe /i "" AGREETOLICENSE=Yes INSTALLDIR=""

The command does not agree to the license and opens the GUI.

I'm using the 6.2.1 UF on x64 Win machines.

I followed the Splunk documentation with no success.

Please use a command line like this - msiexec /i splunkforwarder-6.2.1-245427-x64-release AGREETOLICENSE=Yes /quiet
The /quiet is to suppress the GUI. You have to specify the msi in the command line which was missing in your invocation.
