I am upgrading an indexer from 7.2.6 to 7.3.9 on a Windows 2012 R2 server.
During the installation near the end of installation I see that the installer is rolling back the upgrade. Where do I find out why the installation is failing?
I've done upgrades in the past, but never have I seen it rollback an installation.
Run the installer from the command line like so:
msiexec /l*vx msiexec.log /i <splunk.msi>
Then search for "return value 3" in msiexec.log and the few lines before that should tell you what is going wrong.
