How To Fix DLL File Missing Errors in Windows 10/11

Fix: DLL File Missing Errors

The problem of missing DLL (Dynamic Link Library) files often arises from situations where the setup DLL file is either removed or becomes corrupted. These errors can indicate various underlying issues, including hardware problems, registry errors, or even the presence of malware or viruses on your Windows 10 or Windows 11 computer.

You might encounter error messages related to missing DLL files when you use or install certain programs, when you start or shut down your Windows computer, or even during the process of installing Windows itself.

It’s important to note that the setup.dll file plays a crucial role in performing specific tasks before and after installing or uninstalling programs.

So, when this file is missing or damaged, it can lead to a range of issues, triggering error messages and potentially affecting the proper functioning of your software and your computer as a whole. Identifying and resolving the root cause of DLL file problems is essential to ensure a smooth and error-free computing experience.

1. Restore setup.dll from the Recycle Bin

One of the most straightforward explanations for encountering a “DLL file missing” error is the accidental deletion of the file.

It’s quite common for users to inadvertently remove important DLL files, which can lead to various software and system issues. Fortunately, in cases where you’ve unintentionally deleted the Setup.dll file, there is a relatively simple solution available.

You can attempt to restore the Setup.dll file from your computer’s Recycle Bin. The Recycle Bin is a temporary storage location where deleted files are kept before they are permanently removed from your system. By accessing the Recycle Bin, you have the opportunity to recover deleted files, including DLL files like Setup.dll.

To do this, open the Recycle Bin, locate the Setup.dll file, right-click on it, and choose the “Restore” option. This action will return the deleted file to its original location on your computer.

However, it’s crucial to exercise caution when deleting files to avoid accidentally removing essential system components like DLL files in the future. Additionally, if restoring the Setup.dll file from the Recycle Bin does not resolve the issue, further troubleshooting steps may be necessary to address any underlying causes of the DLL file problem.

2. Run Viruses and Malware Scan

Malicious software, often called malware or viruses, can be the reason why you see those “DLL file missing” errors on your computer. These harmful programs can mess with your files, including important DLL files that your computer needs to run smoothly.

To make sure your computer is safe and to fix these errors, you can do something called a computer scan. It’s like a checkup for your computer. You use a special tool, like an antivirus or antimalware program, to scan your computer thoroughly. This tool looks for any malware or viruses that might be causing problems, including those missing DLL files.

Once it finds them, it can remove or fix the bad stuff, which can often solve the “DLL file missing” errors. So, running a computer scan is a good way to keep your computer healthy and free from these errors. Make sure your antivirus software is up to date. You can download a free Malware detector tool.

3. Perform System Restore

When you’ve exhausted all other avenues and none of the previously attempted solutions have resolved the persistent “DLL file missing” error, there’s another potentially effective approach you can consider.

This involves using a feature called System Restore to revert your computer to a previous point in time when it was functioning correctly.

System Restore is a valuable tool that allows you to roll your computer’s settings and system files back to a state from the past, effectively undoing recent changes that might have caused the DLL file problem.

This feature creates restore points at various intervals, such as before software installations or significant system updates, which serve as reference points for returning your computer to a stable state.

It’s essential to exercise caution when using System Restore, as it can also result in the loss of recently installed software and changes made to your system settings.

Therefore, it’s advisable to create a backup of your important files before proceeding with a System Restore. If this method proves successful, it can be a valuable solution to finally overcome the troublesome “DLL file missing” error and restore your computer’s functionality to a stable state.

• Type “System Restore” on the Windows search box
• Click on “Create a Restore Point”.

• Click on System Restore under the “System Protection” tab.

• It will prompt you to select a certain date and open the restoring window.

• If you previously created a restore point, you should utilize it; otherwise, the computer will display a recommended date for restoration. Then click “Finish” to complete the process.
• The finishing time is a few minutes. When finished, your computer will reboot.

4. Reinstall the application

Many computer users often turn to the option of reinstalling applications as a viable strategy to address the persistent “DLL file missing” problem.

This approach involves a systematic process of completely removing the software associated with the DLL file issue and then reinstalling it from scratch. It’s a method that can prove effective in resolving this particular error.

Reinstalling the software serves as a kind of “reset” for the application, which can help rectify any underlying issues related to DLL files.

By doing this, you ensure that all the necessary DLL files associated with the software are properly installed and configured. It essentially provides a clean slate for the application to operate without any lingering DLL-related issues that may have contributed to the error.

• Open the “Control Panel” and select “Programmes and Features” to uninstall the program.
• Next, choose the program and then perform a right-click.
• To continue, select “Uninstall” next.

5. Try Windows Update

Ensuring that your Windows operating system remains up to date with the latest updates and patches is a pivotal aspect of maintaining the health and functionality of your computer.

These updates are regularly released by Microsoft to address a multitude of issues, including critical bug fixes that can directly impact the smooth operation of your system.

One prevalent issue that these updates aim to mitigate is the dreaded “DLL file missing” error, which can disrupt various software applications and impede your computing experience.

By keeping your Windows OS up to date, you are essentially equipping your computer with the most current and stable versions of system files, including DLL files.

• Open Settings using Win + I hotkeys.
• Choose Windows Updates from the left pane.
• Click on the Check for Updates option.
• Wait until Windows downloads all the available updates. Once done, reboot the system and check for the problem.

6. Fresh installation of Windows

In the event that none of the aforementioned methods prove successful in rectifying the persistent “DLL file missing” issue, it may be prudent to consider a more comprehensive approach: reinstalling Windows from scratch.

This particular course of action involves a complete reinstallation of the Windows operating system, essentially wiping your hard disk clean and starting anew. Reinstalling Windows is often viewed as a last resort, but it can be an effective solution when all other troubleshooting avenues have been exhausted.

This approach offers several benefits, chiefly among them the assurance that your operating system will be in a pristine state, free from any lingering DLL file problems or software conflicts that may have been causing the error.

The process involves booting your computer from a Windows installation media, such as a bootable USB drive or DVD, and following the on-screen instructions to initiate the installation.

During this process, you’ll have the option to format and erase your existing hard disk partitions, effectively removing all data and software from your computer.

• Restart your computer after inserting the installation disk.
• When the computer boots into BIOS, press a certain key (often F2 or F11) to change the boot order so that your computer boots from the installation disk.
• When the page has loaded, click Install now, and then proceed as directed to finish the procedure.​

7. Run Startup Repair

A built-in startup repair tool in Windows 11 is intended to find and fix DLL file missing issues you might be experiencing. Take the actions listed below to launch Windows startup repair:

• Using a bootable device or a force restart, boot your Windows 11 to WinRE.
• Navigate to Troubleshoot > Advanced > Startup Repair.
