My QuickBooks says error code 80029c4a. What is it, and how to fix it?

Question

The dynamic link library, commonly known as the DLL file, consists of essential files required to run QuickBooks. In case the DLL file gets corrupted, then it leads to QuickBooks error 80029C4a. The other reasons causing error 80029C4a are incorrect antivirus or firewall configuration, and another third-party software is hampering QuickBooks desktop functioning. To eliminate this problem, you must add QuickBooks in the exception’s list of antivirus programs so that the QuickBooks files shouldn’t get quarantined. If you have already done it, then use the QuickBooks installation to eliminate the problem. For that, go to the settings and then click apps and features. Search for QuickBooks, click modify from the list of installed apps. After that, you will get an option to repair the QuickBooks installation. If QuickBooks error code 80029C4a still persists, then you will need to perform a fresh QuickBooks installation.
