i have used this script with previous versions with no issues
msiexec.exe /i splunkforwarder-7.3.1-bd63e13aa157-x64-release.msi DEPLOYMENT_SERVER="mydeploymnetserver:8089" SPLUNKPASSWORD="mypassword" AGREETOLICENSE=Yes /quiet
when i try with the new forwarder it does nothing and does not even log anything to C:\Windows\Temp\splunk.log like it normally does when you do this install
is there something new with 7.3.1 that is required for the script to work
Does it give more info if you remove the the /quiet switch at the end?
