Many settings and configurations of QuickBooks Desktop lead to encountering QuickBooks error 12002. So, users must refer to the solutions provided below to fix this error:

Solution 1: Test connectivity and settings

You must ensure that Internet Explorer is your default browser. QuickBooks accesses the Internet via this browser. Hence, you must also keep checking this browser with other websites.

Internet Explorer is what QuickBooks uses to access the Internet, so it needs to be the default browser. You should also check if you can access other websites as well.

You must download TLS 1.2 Utility and run the program. Recheck whether you can open secure websites other than QuickBooks. Apart from this, you must contact an IT expert if you are unable to open any other secure website other than QuickBooks.

You may face downloading update issues because of incorrect settings of Internet Explorer. In order to verify the Internet Explorer’s settings, refer to the pointers below.
