Lisa, a small business owner was trying to update QuickBooks to the latest version to
ensure compliance and access new features. However, an error message stating, “QuickBooks
Error 12002” appeared on her system screen, preventing completion of the update. The error
occurred because QuickBooks could not establish a stable internet connection, which made
Lisa realize that her network settings were misconfigured, which had further blocked

Internet Explorer is set as the default browser. After making this adjustment, she was
successfully able to update QuickBooks, rectifying QuickBooks error 12002. Keep reading
