Solution 3: Manually Fix Windows Components

Step 1: Manually Repair or Reinstall Microsoft .NET Framework

Microsoft technologies power QuickBooks Desktop's web-based features. One of the most significant of these is the Microsoft.NET Framework. QuickBooks' smooth operation may be hampered if this framework has problems.

Regarding Windows 10 and Later Versions

• Make sure that every open program has been closed
• Navigate to the Windows Start menu
• To access the Control Panel, type it into the search bar and click
• Choose Programs and Features
• Click the button labeled Uninstall a Program. Make sure nothing will be removed
• Choose whether to activate or deactivate Windows features
• Look for the .NET Framework on the list

Talking about .NET Framework 4.5

If the .NET framework 4.5 checkbox is left unchecked

• Check the box to activate .NET Framework 4.5 (or the appropriate version)
• To save your changes, click OK
• Give your computer a restart .NET Framework 4.5 is unchecked
• To confirm the changes, click OK
• Restart your device
• Follow the previous steps to reactivate .NET Framework 4.5

Once you are back in Windows, adjust the .NET Framework 3.5 SP1

• If the option for the .NET Framework 3.5 SP1 is not selected:
• To activate it, check the box
• To accept the changes, click OK
• Launch the system from the beginning

If the box next to .NET Framework 3.5 SP1 is already checked:

• Uncheck the checkbox to deactivate it
• Click OK to confirm your selection
• Restart your computer
• Go back into Windows and enable the .NET Framework 3.5 SP1 by following the steps

The issue might be with the operating system rather than QuickBooks. If you still receive an error message, follow the next step.

Step 2: Repair Microsoft MSXML

Microsoft defines its XML Core Services (MSXML) as a set of services that allow you to create XML-centric Windows applications using Script, VBScript, and other Microsoft tools. Due to MSXML errors, QuickBooks Desktop may not function as intended.

Among the mistakes you might encounter are:

• QuickBooks encountered a problem when attempting to use this registration document. Verify that MSXML 4 is installed correctly: All Users\Application Data\COMMON FILES\Intuit\QuickBooks\QBRegistration.dat in C:\Documents and Settings.
• Absence of activity during the installation process at MSXML 4.0 installation
• It can be difficult to register msxml3.dll or msxml4.dll on 64-bit devices
• There is no registration assistance available for this specific file category
• Make sure your system is configured correctly for MSXML 4
• There was an irreparable mistake. Exception: QuickBooks Error 1603: MSXML was unable to create an instance. The filename.dll cannot be executed

You can proceed if you can install and launch QuickBooks. If issues persist, proceed to Solution 4.
