Can't start BI

Hi

after starting the bat file :

C:\biserver-ce>start-pentaho.bat

I get that response:


DEBUG: Using PENTAHO_JAVA_HOME
DEBUG: _PENTAHO_JAVA_HOME=C:\Program Files (x86)\Java\jre1.8.0_51
DEBUG: _PENTAHO_JAVA=C:\Program Files (x86)\Java\jre1.8.0_51\bin\java.exe
Using CATALINA_BASE: "C:\biserver-ce\tomcat"
Using CATALINA_HOME: "C:\biserver-ce\tomcat"
Using CATALINA_TMPDIR: "C:\biserver-ce\tomcat\temp"
Using JRE_HOME: "C:\Program Files (x86)\Java\jre1.8.0_51"
Using CLASSPATH: "C:\biserver-ce\tomcat\bin\bootstrap.jar"

Then a window opens and closes immediately. The tomcat\logs directory contains only a desktop.ini file. Are there any logfiles that I can check to understand what went wrong?

Any help would be much appreciated.
