## Why Won't Arelle Open?

Running into trouble opening Arelle? It might be a pesky corrupt configuration or
a missing installation file causing the problem. Don't worry! Usually, a [clean install][clean-install]
will set things straight. If that doesn't do the trick, please don't hesitate to
[report a bug][bug-report]. We're here to help, and we'll get to the bottom of it!

## Why Am I Getting a Validation Error or Warning?

Disagree with an Arelle validation? Open a [change request][change-request] with
a document that triggers the rule and we'll take a look. Some jurisdiction based
validation rules are open to interpretation. In these cases we defer to the community
for consensus.

## Why Are Concept Details Missing From the Viewer?

Concept details missing from the Arelle ixbrl-viewer or Edgar Renderer? Check the
Arelle log for download errors. If Arelle can't download the referenced taxonomy
and schemas that define those concept details the viewers will fail to render them.

## Is There a Newer Version of Arelle Available?

New versions of Arelle are typically released multiple times per week. If you're
using one of the [prepackaged distributions][prepackaged-distributions]
you can check for and install updates from the Help menu in the GUI.
