# Scanning plugin problems

> Fix ABBYY FlexiCapture scanning plugin failures caused by disconnected sessions on shared machines, by restarting or ending the ScanningPluginBR.exe process.

Scanning documents on a web station requires the [ABBYY Scanning Plugin](/flexi-capture/web-stations/scan-station-plugin).

## Why a shared machine breaks the plugin

The plugin does not support concurrent use by different operators. Each operator sharing a machine has to sign out when they finish.

Failing to sign out leaves a disconnected session behind. Other users' web stations then send their requests to the HTTP server of that disconnected session, and the scanning plugin stops working.

## Recover the plugin

Use any one of these:

* Restart the machine. This closes all sessions, and the plugin launches under the correct user.
* End the `ScanningPluginBR.exe` process in Task Manager, which needs administrator privileges. This avoids a restart.
* Run `ScanningPluginBR.exe /server`. This ends both the process and the session, and the plugin launches under the current user.

<Info>
  `ScanningPluginBR.exe` sits in `%ProgramFiles%` when a system administrator installed the plugin, and in `%USER%\AppData\Local\ABBYY\ScanningPlugin\3.0` otherwise.
