How do I edit my code for a universal forwarder silent installation on Windows via CLI?

[timospringer]

Hello,

This is my code for installing and updating the UniversalForwarder via the command line.

msiexec.exe /i "\\splunkforwarder-6.2.4-271043-x64-release.msi" AGREETOLICENSE=Yes /quiet

This works perfectly fine for installing and updating the forwarder.
However, it doesn't work when the same version of the UniversalForwarder is already installed. After executing, I can't even find the UniversalForwarder in my Program Files.

Does anyone know how to optimize the code?

Hi,

seems like you want a forced install.
There are several options. Check:

Hi Jens,

thank you for your answer! It solved one problem, but made another. 😉

My problem is, that this command doesn't work when the UniversalForwarder isn't installed on the machine.
I need a script where the Forwarder is installed when it's not on the machine but doesn't make problems when it's already installed.
