Hi,
The VDF Admin Tool doesn’t depend on Tomcat, so that warning about Tomcat you are seeing is unrelated. I’d recommend you look in the **<DENODO_HOME>\logs\vdp-admin\vdp-admin.log** file while you are trying to start the VDP Admin Tool and see if any errors occur that might be related. You could also run the **vdpadmin.bat** script directly, from the **<DENODO_HOME>\bin** directory and see if that works.
Hope this helps!
