Error 15241 typically indicates that QuickBooks is encountering a problem verifying the digital signature of the payroll update file or that a necessary component for the update process is not running or is malfunctioning. This digital signature acts as a seal of authenticity, ensuring the file originates from Intuit and hasn’t been tampered with. When this verification fails or a crucial service isn’t active, QuickBooks understandably halts the update to protect your system’s integrity.
