EventReporter Event ID 100: The service was installed#

Answer#

The Windows service registration completed.

Event details#

Event ID: 100
Severity: Information
Component: Windows service lifecycle
Windows Event Log source: Adiscon EvntSLog
Available since: Current supported versions; original introduction not recorded
Message pattern: The {service_name} service was installed.

Possible causes#

A product installation or explicit service-install operation registered the Windows service.

Immediate checks#

No repair is required when service installation was intended.
If the registration was unexpected, identify the installation or administrative action that occurred at the same time.
Verify the registered service name, executable path, start mode, and service account before starting it.

Detailed procedures#

Verify service state, dependencies, and service account — Confirm service state, start mode, dependencies, account, and SCM errors.
Collect an Event ID and neighboring product events — Preserve the complete event and the product events immediately before and after it.
Export configuration and collect a bounded debug log — Create a text configuration export and time-bounded debug capture, then disable debugging.

Verify the result#

Confirm that Windows reports the intended service registration and that the service can enter the Running state.

Evidence to collect#

The complete Windows Application Event Log entry, including all event detail.
The product name, exact version, service account, and event timestamp with time zone.
A configuration export and debug log covering the same time window, with secrets removed.

Escalation#

This event normally records state rather than a failure. Escalate only when the state was unexpected or the associated operation does not recover.
