DLL errors are basically any error that involves a DLL file, which are files with a .DLL extension.

DLL errors can and do appear in all of the latest Microsoft Windows operating systems, whether it be Windows XP, Vista, 7, 8 or 10.

DLL errors can be quite numerous; this is because of the sheer number of DLL files floating around your computer, as each individual file has the potential of contracting some kind of problem. Fortunately, I have put together a number of steps that you can use in order to fix the vast majority of DLL errors.

Note: These are general steps that one should take, however in certain situations it may be more prudent to search for help on the specific DLL file that you are having trouble with.

Restart Your Computer

Whenever you encounter any error on your computer, the first thing you’ll want to do is restart the system, this is because the issue may only be temporary. No point trying to fix a problem that doesn’t really exist.

Note: This option will only work if the DLL error you are encountering is not prohibiting your system from booting up. In more serve cases, you may be required to hard reset your system.

Download the .DLL File

In some cases, it may be possible for you to fix the DLL error by simply copying the damaged .DLL file from a working computer to your troubled system. However, because DLL files are, in most situations, quite serve, it is possible that doing so could lead to more problems for your computer.

That said, there are many DLL download websites that you may want to consider, typically they’ll contain a library of downloadable .DLL files which you can copy to your system. Just make sure you copy over the correct version of the file, when doing so.

Use Safe Mode

If the DLL error that you are encountering is preventing you from booting into your computer, then you may want to consider booting into Safe Mode to fix your system.

Booting into Safe Mode is a fairly simple process, simply press the F8 Key right after the POST (Power on Self Test) and an Advanced Boot Options menu will pop up, from there, select Safe Mode with Networking and it should load up.

Use System Restore

Before attempting any of the more, sophisticated solutions, I recommend you first try System Restore. If you don’t know what this tool is, basically it’s a Windows restoration feature, which is capable of sending your system back to a previous state, in this case, when the computer was working correctly. In order to load this tool, simply do the following:

1. First, you will need to boot either into Safe Mode or Normal Mode with administrative rights.

2. Then press Windows Key + R, to open the Run Command Box and type rstrui.exe (Windows XP: %systemroot%\system32\restore\rstrui.exe) into it and click on OK.

Run Command Box

3. Follow the onscreen instructions to utilise an available restore point.


Use System File Checker

Another tool that is capable of fixing DLL errors is the built-in System File Checker. This tool will scan your system for damaged and/or missing system files and replace them were applicable. To run this tool the end user need only do the following:

1. Boot into your computer with a user profile that has administrative rights.

2. Then press Windows Key + R, which will open the Run Command box, then type cmd into it and click on OK.


3. Once Command Prompt loads up, type sfc /scannow and press Enter.

type sfc /scannow and press Enter

Note: System File Checker will now run and verify that all the system files are intact. In some situations, you may be required to put your Windows CD into your CD ROM drive.

DLL Error Is With a Specific Program

If you experience the DLL error whenever you open a specific program, it’s highly likely that the problem is with that program. Resolving such errors tends to be much simpler than repairing operating system based errors.

If the program only recently started to give you problems, then you should consider reinstalling it. In addition to that, you may also want to ensure the program is up-to-date with the latest updates and patches applied to it.

DLL Error Occurred When Program Uninstalled

If you started experiencing your DLL error, only after uninstalling an application from your computer, then the error is likely the result of a required file being removed, during the uninstallation process.

In this particular situation, I’d recommend reinstalling the application you just removed, to restore the file that was removed when you uninstalled it. If this action successfully repairs the problem, then you’ll want to remove the program again, but this time, when given the option during the uninstall process, click on No or No to all. This will ensure that the uninstaller only removes the files crucial of the application, leaving behind any common/shared files.

DLL Error Occurred When Program Installed

If you started experiencing your DLL error, right after you installed an application then I’d recommend you checked whether there were any updates for this new program. There are situations when an application requires an update before it will work as specified. You can usually find these updates on the website of the program developer.

If you are unable to find any updates for the program, then I’d recommend you uninstalled the application. Of course, this will mean you won’t be able to use the program, so I’d also recommend you consulted the product developers for help on how to get the program to work correctly on your computer.

Malicious Files on Your Computer

Malicious files, such as spyware, adware, malware, viruses, are all capable of getting onto your system and causing DLL errors. Thus, it’s recommended that you regularly run a full virus scan of your computer.
