# Crashing on startup

If OmniScope crashes or fails to launch, the most likely cause is a corrupted configuration file.

To manually reset the config, delete these files:

* **config\_1\_10.json** or **config\_1\_11.json** (depending on the version you are using)
* **ui.ini**

from the following directory:

```
Windows:
C:\Users\USERNAME\AppData\Local\NobeOmniScope

macOS:
~/Library/Application Support/NobeOmniScope
```

OmniScope will start with factory settings after that.

If the application still crashes, try resetting your saved layouts as well — delete the layout files from the same directory and create new ones from scratch.
