Symptoms

1. Install or update 360Suite with Tomcat running as a Windows service.

2. Attempt to launch or interact with the 360Suite Administration Console.

3. Notice that the console does not load properly or crashes silently.

Cause

The Windows user account running the Tomcat service does not have the necessary permissions to access required Windows registry keys.

Specifically, the following registry path is commonly affected:

HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs

Without read/write access to this key, Java-based preferences required by the Admin Console may not function correctly.

Resolution

1. Open the Registry Editor with administrator privileges: Press Win + R, type regedit, and hit Enter.

2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs

3. Right-click the Prefs key and choose Permissions.

4. Locate the user account used by the Tomcat service (e.g., Local Service, Network Service, or a custom user).

5. Grant Full Control permission to this user.

6. Click Apply and OK to save changes.

7. Restart the Tomcat service to apply the updated registry permissions.

Additional information

• These permission issues are specific to Windows environments.

• You can confirm the Tomcat service account by opening services.msc, locating Apache Tomcat, right-clicking → Properties → Log On tab.

• Always backup the registry before making changes.
