### **yuzu starts with the error "Unable to start application: Os { code: 2, kind: NotFound, message: “The system cannot find the file specified.” }"**
_This problem is usually caused by a false positive of your virus scanner, most recently avast and awg._
_You can confirm it is a false positive with an online scanner such as VirusTotal if you wish._
_To fix this you'll need to either disable or uninstall your virus scanner. Make sure to reboot if you choose to uninstall it._

_For a list of useful mods for your favorite games, check our database with [Switch Mods](https://yuzu-emu.org/wiki/switch-mods/)_

_`Mod directory/mod name/romfs`_
_or_
_`Mod directory/mod name/exefs`_
_The mods provided on our [Switch Mods](https://yuzu-emu.org/wiki/switch-mods/) page are already structured accordingly and only need to be extracted into the mod directory folder as is._
_Once added to the correct mod directory, simply right click the game again, select properties and activate the installed mod. The same process can be followed in reverse for de-activating mods_
### **How do I uninstall game updates or DLC?**
