Hello, @DAK3.

Let's fix the error message you've encountered when opening QuickBooks Desktop (QBDT) so you can use the program and get back to business in no time.

The error message 80029c4a occurs when QuickBooks components are blocked from loading essential files in your computer. When you see this error and can’t open QBDT, update the software to its latest release. This ensures you have the latest features and product improvements.

If the error continues, you need to check your antivirus software and the area of your program that lists blocked files (sometimes called your “quarantine”). Once you see any QuickBooks programs (like, AutoBackupExe.exe; Dbmlsync.exe; or DBManagerExe.exe, etc.) in the quarantine, give them permission to go through your firewall. Please note that most of these files are located in C:\Program Files\Intuit\QuickBooks (year). Files with (x86) in the location, such as C:\Program Files (x86)\Intuit\QuickBooks 20XX, are 64-bit versions.

If you still get the error after performing the troubleshooting steps above, reinstall QBDT to refresh the program files. For the complete guide, please refer to this article: Fix Error Code: 80029c4a for QuickBooks Desktop.
