# Uninstalling the Add-On: Fixing Errors

Note: The Save & Load Add-On is included within the Inventory Pro Add-On files when using the Inventory Pro Add-On. Consider this before making any changes

To uninstall the **Inventory Pro Add-On**, simply deleting it will lead to errors. This is because, during installation, **Define Symbols** are assigned to the project, enabling FPS Engine to run conditional code based on the presence of the Inventory Pro Add-On.

After removing Inventory Pro Add-On´s folder from the **Project** folder, many errors will be thrown. Then, navigate to **Edit > Project Settings > Player**, as seen in the Picture below:

Then, click on _**Other Settings**_ to unfold additional settings. Scroll down until you find the Script _**Compilation Section**_, where _**Scripting Define Symbols**_ are defined. Between them, you´ll find **`INVENTORY_PRO_ADD_ON`**. Select this Define Symbol, then click on the **`"-"`** Icon and `Apply` the Changes as the Picture below suggests:
