[KB7801] Apache Tomcat installed from ESET PROTECT All-in-one installer is unable to extract the 'era.war' file contents (8.x–10.x)


  • The ESET PROTECT Web Console is inaccessible after the ESET PROTECT Server was installed using the All-in-one installer.
  • The era.war file located at %ProgramFiles%\Apache Software Foundation\Tomcat_folder\webapps was not extracted into the era directory (Replace Tomcat_folder with the actual folder name in your system).


This issue occurs on Windows Server installations and is caused when the Apache Tomcat service is being logged onto as a Network Service. 


  1. Click Start, type services.msc and then press ENTER.

  2. Right-click the Apache Tomcat service, and select Stop from the context menu.
