Error "ensureSsPid" from serch- server. Appian 17.4

I'm runnig Appian from Windows 10,

mysql-installer-community-5.7.20.0

I´m able to start appian services, but when i start the search-server i see in the console the following message "El sistema no encuentra la etiqueta por lotes especificada: ensureSsPid",

if i try to start it again, i see "The Appian Search Server is already running." 

Next, I run Jboos, it starts, but I can´t loggin  into "http://<FQDN>:8080/suite", i get an authentication error, i try to log with the user added in "passwords.properties " file.

Regards.
