# SY01003: Permission Denied

## What This Means[​](#what-this-means "Direct link to What This Means")

The POS application doesn't have permission to access a required resource. This could be a file, folder, or system feature.

## Common Causes[​](#common-causes "Direct link to Common Causes")

* **File permissions** — Can't read or write to needed files
* **App permissions** — Application lacks required permissions
* **Protected folder** — Trying to access a restricted location
* **Security software** — Antivirus blocking access

## How to Fix[​](#how-to-fix "Direct link to How to Fix")

### 1. Run as Administrator (Windows)[​](#1-run-as-administrator-windows "Direct link to 1. Run as Administrator (Windows)")

Right-click the app and select "Run as administrator" if needed for initial setup.

### 2. Check Application Permissions[​](#2-check-application-permissions "Direct link to 2. Check Application Permissions")

**macOS:**

* System Preferences → Security & Privacy → Privacy
* Check that the app has necessary permissions

**Windows:**

* Settings → Privacy
* Review app permissions

### 3. Check Folder Permissions[​](#3-check-folder-permissions "Direct link to 3. Check Folder Permissions")

Ensure the app can access its data folder:

* The user should own the app data directory
* Write permissions should be enabled
* No read-only flags on the folder

### 4. Review Antivirus Settings[​](#4-review-antivirus-settings "Direct link to 4. Review Antivirus Settings")

Security software may block access:

* Check antivirus logs for blocks
* Add the POS app to the allowlist
* Whitelist the app data folder

### 5. Reinstall the Application[​](#5-reinstall-the-application "Direct link to 5. Reinstall the Application")
