SY01003: Permission Denied

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​

  • 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​

1. Run as Administrator (Windows)​

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

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​

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​

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​

Check for unsaved work first

Clearing local data or reinstalling the app deletes anything on this device that hasn't reached your store — including sales taken while offline, open carts, and edits that didn't save. Before you clear anything, open Store health → Database and check nothing is listed as held or as never having reached your server, then Store health → Logs for 0 stuck records and 0 changes waiting to send; then finish or note every open cart. If your WCPOS has no Store health page, update WCPOS first, then check. If anything is listed or waiting, or you can't check, don't clear — ask your store owner or contact support.

Only if permissions are corrupted, and only after the check above:

  1. Uninstall the POS application
  2. Restart your device
  3. Reinstall to a standard location
  4. Run with normal (non-admin) permissions
