[KB7801] Apache Tomcat installed from ESET PROTECT On-Prem All-in-one installer is unable to extract the 'era.war' file contents (Windows)

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 into as a Network Service.

Click Start, type services.msc and press Enter.
Right-click the Apache Tomcat service, and select Stop from the context menu.

When the process is stopped, right-click Apache Tomcat again and select Properties from the context menu.

Navigate to your Tomcat directory (directory location and name may differ):

C:\Program Files\Apache Software Foundation\Tomcat_folder
Open the webapps folder.
Delete the existing era.war file and copy the era.war file from the All-in-one installer files into webapps (C:\Program Files\Apache Software Foundation\Tomcat_folder\webapps).

Click Start, type services.msc and press Enter.
Right-click the Apache Tomcat service and select Start from the context menu.
Allow the file to complete extraction; this can take several minutes. After the extraction is complete, verify that you can log in to the ESET PROTECT Web Console (the default address is https://localhost/era). Close the ESET PROTECT Web Console when you are finished.
Stop the Apache Tomcat service again.
Right-click the service and click Properties.
In the Log On tab, select This account. Type "Network Service", erase both password fields and click Apply → OK.
