The message is accompanied by ‘OK’ button. When the user clicks this button, they see another error message saying: ” QuickBooks couldn’t load a system component. Restarting your PC might solve the problem. Error type: 80029c4a – Cannot load DDL (dynamic link library)”.As the message suggests that DLL is the main cause behind the problem.

1. Restart your Pc:

If you rarely reboot your PC but put it to “sleep” mode instead, this may help you.
Rebooting the device helps to clear out memory complications and give your installed applications a new start.

2. Update your finance software:

Intuit gives its users free QuickBooks updates during the life of a product.It can be installed automatically or at the moment as per your comfort. Usually, these updates remove application problems by fixing bugs and internal issues (that you might even know about). But be careful while going for an update,if used on networked systems. In such a situation, if you update, you could be starting a forced update for all users, since all the network devices should be working with the similar release of a software.In the working hours, it may create unnecessary delays and halt.

3. Run “reboot.bat”:

When you install QB software, a small batch file named ‘reboot.bat’ is stored in the installation directory. No matter, which version you are using, you will always see this file. Its purpose is to reset all the system settings that software makes over the period of its usage. ‘Reboot.bat’ has command line programs that help to reset Windows registry settings for all the components that the accounting software uses. Thus, we can say, it’s a type of clean-up utility that put everything in their right
place (in case, they ever get messed up).Before running the file, make sure that no instances of QB are running. Same applies to networked systems too.There shouldn’t be a single active instance of QB software running at the time when
‘reboot.bat’ is executed. Also, remember that to run the file, you have to log on to Windows as administrator.

4. Re-launch QuickBooks:

Sometimes, a simple restart helps you overcome the problem. You must go for it once if positive results are not obtained by trying all the above techniques.

If using the software on a standalone machine,things could be simpler. On the other hand, on networked systems, there is a need to follow the same caution that you performed while updating the software.Go with given steps to repair software installation:

  • Look for a machine that’s not available on the network
  • Then, launch QuickBooks on it. Next, see for its license and product number by clicking ‘About’ option on the menu.
  • Open Control Panel and move to the list of installed programs
  • There search for ‘QuickBooks’ in the list. After selecting it, please click on ‘Uninstall’
