# Automating applications running in AppContainer mode

> Automating an application running in AppContainer mode fails by default.

## Description

Automating an application running in AppContainer mode fails by default.

## Cause

The application running in AppContainer mode is trying to access files from `C:\Users\User\.nuget\packages\uipath`, but it doesn't have access to that folder.

## Solution

You need to grant a specific user (`ALL APPLICATION PACKAGES`) **Read & execute** permissions for the UiPath NuGet folder of the current user.

To do so, follow these steps:

1. In Windows Explorer, go to `C:\Users\User\.nuget\packages`.
2. Right-click on the `uipath` folder. The folder **Properties** window appears.
3. Go to the **Security** tab.
4. Add the `ALL APPLICATION PACKAGES` user and grant them **Read & execute** permissions.
5. Click **Apply** and close the Properties window.

You can now automate applications running in AppContainer mode.
