# Troubleshooting

## MAV Logs and additional information

When reporting a MAV application issue to <support@akoyabio.com>, we may request logs and additional information to help facilitate resolving the issue. Step-by-step instructions for retrieving logs and additional information (MAV version, FIJI/Java version, system information, etc) can be found in the following document:&#x20;

{% file src="/files/-M8IZjLcqDO9CTuKnhey" %}

By default, MAV logs are located here:

**Windows OS:      C:\Users\\\<username>\Codex\MAV logs**

**Mac OS:               \<user-home>/Codex**

If log files are not present, MAV logging can be enabled by doing the following:

1\) Run **CODEX® MAV**

2\) From the menu bar, go to **Tools -> Preferences**

3\) Ensure that **File logging** is checked and Verbosity level is set on **Debug**

## How do I update a FIJI plugin if it fails to update automatically?

Indications that a plugin has failed to update in FIJI include error messages such as those shown below.&#x20;

1. After clicking **Help -> Update** you may see the following:

![This indicates that your old plugin was not replaced with the new version.](/files/-M7YhRMeLfetjoAwtQb2)

2\. **Delete** the conflicting versions. Once the conflicting versions are deleted, Click **OK.**

3\. Select **"Apply changes"** to update the software and then **restart FIJI.**

4\. When **FIJI restarts**, you may still see an error message.

5\. Click **OK** and **close FIJI**

6\.&#x20;
In Windows Explorer, navigate to the **FIJI-win64** folder and Open the **"plugins"** folder.
