I am trying to run the BitBucket upgrade in unattended mode by passing in a varfile and using the -q flag. The installer launches, as verified by using Windows task monitor, but then shuts down after about 10 seconds. There are no errors displayed to the console window, nor any log files being created that I can see. If I run the installer in console mode, everything looks correct and runs through completely, so I am not sure what is causing the failure.
Is there a way to get logging enabled for the unattended upgrade?
