Many people attempt to repair DLL files (dynamic link libraries) that are corrupted or missing by downloading new versions of the file. However, this PC repair approach is prone to error and could possibly even cause virus damage. In this article, we take a look at some of the software tools used for DLL repair and five of the more common & safe approaches you should consider first before resorting to downloads.

How to repair DLL files using your own utilities

It is often possible to repair DLL errors by understanding where the root cause of the problem is. Here are five suggestions/repairs that you can attempt:

  1. Run an anti-virus scan: A malicious virus (e.g. a malware application) can cause damage to the registry and system files which affect how DLLs are referenced and being used. Scan the full hard drive and remove any bugs that are found.
  2. Check your registry: Anti-virus applications can only find a small percentage of issues. For example, corruption to an address attribute in a registry key can often result in “missing DLL” exceptions being thrown even when the DLL is in its correct location. Use a registry cleaner (e.g. Registry Easy) to automate the process of scanning for damage.
  3. Application updates: If the DLL belongs to one single application on your system then try getting the latest updates for the program. A patch update will often include DLLs as these tend to change quite often. Installing the update will also mean that many of the registry key settings will be updated too.
  4. Windows updates: Similar to the previous step, the Windows update service include patches for many operating system programs that invariably include new DLL file versions. It is worth attempting to repair OS DLL files this way, but its success rate is not always good (as patches do not always include all of the DLLs on your system).
  5. System File Checker: Windows 2000/XP have one extra utility they can try out. The system file checker (enter sfc.exe as a DOS prompt) can be run to scan for damage to OS files and programs.

The final word on using downloads to do a DLL repair

If you do end up deciding to repair DLL errors by downloading and installing a new version of the dynamic link library then there are three key precautions you should make:

  • Make a backup copy of the DLL you replace just in case you need to rollback the change.
  • Always make sure you are downloading/installing the correct version of the DLL.
  • Only use reputable download websites to obtain your DLL’s. Some hackers actually created websites to make DLLs available that incorporate malicious malware applications.
