QuickBooks Payroll Error 15409 typically occurs when updating payroll or during the installation of a payroll update. This error is associated with digital signature issues that prevent QuickBooks from verifying the files required for the payroll service update.

Causes:

1. Incorrect Internet Explorer settings.
2. QuickBooks installation files being damaged.
3. Misconfigured Windows settings or a corrupted file.

Solutions:

1. Reboot QuickBooks: Close and restart QuickBooks. Try updating again.
2. Re-register .DLL files: Open Command Prompt and register the .DLL files by typing “regsvr32 /s” followed by the file name.
3. Reinstall QuickBooks: Reinstall the software using a clean install to resolve corrupt files.

These steps should resolve the error and allow successful payroll updates.
