Hey there,
I mentioned this on Discord, but it was suggested I post a feature request here as well. Currently, the tcadmin2install.exe is automatic for the most part, however it pops up a browser window when it's finished. For those of us automating the deploy process with scripts, this makes it tricky to know when the installation is done. We are unable to wait for the process to complete, because tcadmin2install.exe launches a browser window and the script waits for that window to be closed before continuing. This leads to a bit of a jury rigged script, where we have to run the installer without waiting for it and setting some kind of sleep time before continuing other operations that require the TCAdmin2 install to be completed. This creates a race condition, which is mitigated primarily by just waiting a longer time, which also increases the time of the installation.
Most Windows installers that are expected to be used in automated deployments come with a "/silent" or "/quiet" command-line argument that makes the installer work without requiring any GUI interaction. It would be nice to have a similar argument for tcadmin2installer.exe that doesn't launch a browser when the install is finished.
