QuickBooks error 12157 exhibits various symptoms like the internet settings or firewall security flashing the error message, and code 12157 or a sluggish PC performance may be another indicator of the error. Other symptoms include input commands getting no response on the PC's operating system, QuickBooks will let the error message with the code pop up on the screen during installation, or the Desktop app may keep crashing.
If the system may freeze frequently and the update process halts, then this is another sign of QB error 12157.
