i am also having the same problema help would be appreciated
I too faced similar error but at step 40 of 40.
However, after sometime figured out that the Initialization succeeded. It took longer time than expected because of hardware available, hence the Server thrown an error.
Not sure, if this helps, but that's my experience.
Please try to find out more info from logs
I am experiencing the same problem. Did you run the tsm tableau-server-obliterate.cmd script prior to trying to fresh install Tableau Server?
NOTE: I am trying to install Tableau Server 2018.2.2 on a Machine that I completely removed Tableau Server 2018.1 from.
