QuickBooks Install Diagnostic Tool | Fix Microsoft .NET Framework, MSXML & C++ Issues

QuickBooks Install Diagnostic Tool is developed to deal with Microsoft .NET Framework, MSXML, And C++ Issues. When you install and run QuickBooks financial accounting software on your Windows computer, the program requires additional software components in order to function properly. Therefore, along with QuickBooks, Windows operating system also requires components such as the Microsoft .NET Framework, MSXML, and C++.

These are installed as dependencies for your QuickBooks to work properly in the Windows operating system environment. However, there are times when some users experience issues with these components and need solutions to fix them. In this article, we will provide you a brief description of each of these components and also, guide you through fixing all possible errors using the QuickBooks Install Diagnostic tool.

What are the Microsoft .NET Framework and its relation with QuickBooks?

Microsoft .NET Framework is a software component, which is developed and released by Microsoft for its range of Windows operating systems. It is made available to Windows users both as update package and manual installation (for system admins and developers). Software programs like QuickBooks etc., require this component to function properly, including the program’s graphical interface.

If some reason, your Windows operating system does not have the required .NET Framework components installed (via Windows update or manually), then your QuickBooks program may run into errors such as:

  • QuickBooks error code 1402
  • QB error code 1603
  • Error code 1722
  • QuickBooks error code 1903
  • QB error code 1904
  • Errors related to corrupt or missing .NET Framework libraries

Thus, in short, Microsoft .NET Framework is a component that is responsible for the proper functioning of a program’s interface in Windows. QuickBooks uses the .NET Framework component in its program. Sometimes, the .NET Framework can become corrupt, which may prevent QuickBooks from installing, opening correctly or functioning in its normal state.

What are MSXML and its relation with QuickBooks?

MSXML is a set of core services that creates a dependency on programs developed using JScript, VBScript and other Microsoft development tools. In contrast to the Microsoft .NET Framework, there are other components as well, which are equally important for your Windows operating system and the software programs you install on your computer.

MSXML (.XML) is an almost universally supported way of exchanging documents and data across applications and platforms. It is a way of organizing information, so users can view data easier. However, this only applies to users viewing the data in a Notepad app or web browser window, not for applications to access them in the background. A fine example is how you can open the qbregistration.dat file in Notepad and see the data. Without MSXML, QuickBooks cannot read it.

Don’t ignore the importance of quickbooks clean install tool because it helps to clean the unwanted data(more information connect with us by dialing (+1-844-397-7462) our support team).

Microsoft has provided a way to interpret the data between the XML document (e.g., qbregistration.dat) and the application (QuickBooks). MSXML reads the XML data in qbregistration.dat and relays it back to QuickBooks Desktop.

Following are the errors you may encounter if MSXML becomes corrupt or is missing:

  • Make sure MSXML has been installed on your system correctly
  • QuickBooks had a problem accessing this registration file. Make sure MSXML is installed correctly: C:\Documents and Settings\All Users\Application Data\COMMON FILES\Intuit\QuickBooks\QBRegistration.dat
  • An unrecoverable error has occurred. Exception msxml could not co-create instance.
  • The install process stays at “Installing MSXML” and does not continue.

What are C++ and its relation with QuickBooks?

The Microsoft Visual C++ Redistributable Package contains library files required to run applications developed with Visual C++, the language in which QuickBooks Desktop was written.

If a computer does not have the correct version of Visual C++ installed, QuickBooks 2016 and later versions will install it automatically.

Following are errors that may occur if Microsoft C++ is missing or corrupt:

  • Microsoft Visual C++ Runtime Library: Runtime Error!
  • Error 1904: [file path / name / extension] failed to register
  • C++ runtime error! C:\Program Files\QuickBooks Online Backup\Onlinebackup.shl
  • Microsoft Visual C++ Debug Error Program: C:\Program Files\Intuit\QuickBooks [Year]\QBW32.exe Abnormal Program Termination
  • The application failed to start because side by side configuration is incorrect.
