# OMrun.exe.config

The `OMrun.exe.config` file contains some configuration data like

* internal configuration data which should not be changed by user.
* the only part which could be changed is the part to configure the behavior of the [license](https://www.omrun.ch/help/license-key.html) validation.\
  If the user starts more OMrun instances in parallel then runtime licenses are available, OMrun will wait a defined \[Wait time] and will then check again if a Runtime License is available to perform the designed checks:

```xml
<appSettings>
 <!-- WaitTime in seconds for re-check parallel running instances. Default 30 s -->
 <add key="WaitTime" value="30" />
 <!-- TimeoutAfter: Max. WaitTime in minutes until application timeout because of too many parallel running instances -->
 <add key="TimeoutAfter" value="60" />
 <add key="ClientSettingsProvider.ServiceUri" value="" />
</appSettings>
```

* Change the "WaitTime" and/or "TimeoutAfter" parameter only!
