QB is widely regarded as one of the most efficient and reliable accounting software solutions for small and medium-sized businesses. However, like all software, it can sometimes experience issues, especially during installation or updates. One such error that often causes trouble for QB users is QB Error 1935.

QB Error 1935 typically appears when you try to install or update QB on your computer. The error message may look something like this:

"Error 1935: An error occurred during the installation of assembly component."

This error is a common issue, but it can be frustrating, as it prevents QB from installing or updating properly. In this blog post, we will explain what QB Error 1935 is, what causes it, and how to fix it.

What is QB Error 1935?

QB Error 1935 is an installation error that appears when QB is unable to install a necessary component required for the application to run correctly. It usually occurs during the installation or update process, and it is commonly linked to issues with the Microsoft .NET framework or Visual C++ components, both of which are essential for QB to function properly.

The error may appear as a pop-up message, and it may stop the installation or update process. This issue can prevent QB from being installed on your computer or cause the application to fail after installation.

Common Causes of QB Error 1935

Several factors can trigger QB Error 1935, but the most common causes are related to problems with system components or files. Here are the typical reasons why this error might occur:

Corrupted or Incompatible .NET Framework: QB relies on the Microsoft .NET Framework to run smoothly. If your .NET Framework is corrupted, outdated, or incompatible with the version of QB you’re installing, you might encounter Error 1935.
Issues with Visual C++ Redistributable: The Visual C++ Redistributable package is another critical component that QB requires. If it is missing or outdated, it can lead to installation errors, including Error 1935.
Damaged Windows System Files: Sometimes, damaged or missing Windows system files can interfere with the installation of QB, leading to errors such as Error 1935.
Incomplete or Corrupt QB Installation: If your previous installation of QB was interrupted or corrupted, it could cause issues when attempting to install or update the software again.
Third-Party Antivirus or Firewall Interference: Security software like antivirus programs or firewalls can block certain installation components, preventing QB from completing the installation process and resulting in Error 1935.
Lack of Proper Administrator Permissions: QB needs administrative rights to install or update on your computer. If you don’t have sufficient permissions, you may encounter installation errors like Error 1935.

How to Fix QB Error 1935

Now that we know the common causes of QB Error 1935, let’s explore how to fix the problem. Here are some solutions you can try:

1. Repair or Reinstall the .NET Framework

Since QB relies heavily on the .NET Framework, errors within the framework can cause installation issues. Repairing or reinstalling the .NET Framework can often fix Error 1935.

What to do:

Press Windows + R to open the Run dialog box.
Type appwiz.cpl and press Enter to open the Programs and Features window.
Scroll down and look for any versions of the Microsoft .NET Framework.
Right-click and select Uninstall/Change, then follow the prompts to repair the installation.
If the repair option doesn’t resolve the issue, uninstall the .NET Framework and then reinstall the latest version from Microsoft’s website.
Restart your computer and try installing QB again.

2. Install the Latest Version of Visual C++ Redistributable

The Visual C++ Redistributable package is essential for QB to work properly. If it is outdated or missing, it could lead to Error 1935.

What to do:

Go to the Microsoft Visual C++ Redistributable page.
Download and install the latest version of the Visual C++ Redistributable package for your system (both the x86 and x64 versions if needed).
Once the installation is complete, restart your computer and attempt to install or update QB again.

3. Run QB as Administrator

Lack of proper administrative privileges can prevent QB from installing or updating. Running QB as an administrator can resolve this issue.

What to do:

Right-click on the QB installer or the application icon.
Select Run as administrator from the context menu.
Follow the installation or update prompts to see if the error is resolved.

Follow the on-screen instructions to resolve any detected problems.
After the tool finishes running, restart your computer and try installing QB again.

5. Disable Antivirus and Firewall Temporarily

Sometimes, antivirus software or a firewall can block the installation process. Disabling your antivirus temporarily can help rule out security software as the cause of the issue.

What to do:

Temporarily disable your antivirus and firewall software.
Try installing QB again.
If the installation is successful, add QB to the exceptions list in your antivirus and firewall, then re-enable the security software.

6. Perform a Clean Boot

A clean boot can help prevent background programs from interfering with the installation process. This can resolve conflicts that may be causing Error 1935.

What to do:

Press Windows + R, type msconfig, and press Enter to open the System Configuration tool.
In the General tab, select Selective Startup.
Uncheck the Load startup items box and go to the Services tab.
Check the Hide all Microsoft services box, then click Disable all.
Restart your computer and try installing QB again.
Once installed, return to msconfig and select Normal Startup to restore your normal settings.

7. Check for Windows Updates

Keeping your Windows operating system up to date can fix issues with system files that might be causing QB Error 1935.

What to do:

Open Settings from the Start menu.
Go to Update & Security > Windows Update.
Click on Check for Updates to ensure your system is fully updated.
After the updates are installed, restart your computer and try installing QB again.
