I am running 8.1.18, trying to install ignition. It is saying " Unable to start gateway". I thought that my gateway had started already in going through the install. Java process exec failed with error code 1: SYSTEMD\_KILLMODE is set to 'process' on the top of the script, but the daemon is running with KillMode=control-group. Can anyone help me to correct this situation. ---

Are you upgrading from a previous version, or is this a clean install? Also, what OS and version are you running? ---

Hello, Kevin, this is going to be a clean install. I removed 8.1.5 from the edge device. Do I need to install it back? The OS windows & ignition 8.1.15. ---

If the OS is Windows why would there be SystemD settings? That's a Linux thing. ---

While uninstalled, go through the various `systemd/system` folders (in `/etc` and various others varying by distro) cleaning out any old ignition files. And make sure you wipe `/etc/ignition`. Then re-install. ---

Phil, lets start at the begin. I receive the edge device. It has on it ignition 8.1.5 running. I run the ignition 8.1.18 to upgrade or install on top of 8.1.5 and at the end of my install I get the error above. ---
