# swllrend.dll corrupted or not extracted

When the **low-level rendering** feature of the PDF Converter engine is enabled (in the PDF settings on the General tab), SWING Seascape will attempt to use the **swllrend.dll** file from the **SwPDFC\Libs** subfolder inside your **Notes Data** folder.

The DLL file is used to provide **enhanced PDF conversion quality**. If the DLL file gets corrupted or if it is not extracted properly it can be added to the Notes installation directory manually.

You can download the swllrend.dll file from this page and copy it to the **SwPDFC\Libs** subfolder\*\*,\*\* which is located in **\<Notes Data>\SwPDFC\Libs**

If you are using an ICAA/HCAA client, copy the DLL file to the ICAA/HCAA client installation folder (typically in **C:\Program files(x86)\HCL\HCAA**)

{% hint style="info" %}
You must **unzip** this DLL file before copying it into the **SwPDFC\Libs** folder
{% endhint %}

If the low-level rendering feature is disabled Seascape will **NOT** attempt to copy the DLL file to your system. Note that in that case, the PDF rendering quality may be somewhat lesser when you are converting Notes application documents. However, the conversion of emails will remain unaffected since the emails are processed using a different method altogether.

{% hint style="info" %}
All instances of Notes software should be closed before the new DLL is copied
{% endhint %}

{% hint style="info" %}
If you don't have system permission to copy the DLL file to the Notes Data folder, please contact your Administrator.
{% endhint %}

{% hint style="info" %}
If needed, the DLL file can also be found and copied from the **SWExternalResources** form in the SWING Seascape database (the form can be accessed using **Domino Designer**).
{% endhint %}

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.swingsoftware.com/seascape-for-notes/troubleshooting/error-messages/error-swllrend.dll-corrupted-or-not-extracted.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
