# KB000004: Creating a log file to troubleshoot installation issues with the Access Manager Service

## Summary

If the Access Manager Service installer fails, you can use the in-built advanced logging capability to generate a detailed installation log of what happened, to help troubleshoot the root cause.

## Resolution

From an elevated command prompt, run the installer EXE with the following arguments

```batch
LithnetAccessMangerService-x64.exe /l*v C:\ams-install.log
```

A detailed log file will be created at the path specified, which can be used to help narrow down the root cause.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.lithnet.io/ams/v2.1/help-and-support/support-articles/kb000004.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
