Many people will try to fix DLL problems by directly downloading new versions of the file. This has the inherent danger of using the wrong version or buggy/virus-infested versions. This article details some of the PC maintenance software tools you can use to repair DLL faults.

Fix DLL files indirectly – faults in other files that affect DLLs

Many of the faults that report to be DLL issues may actually be indirectly related to the file. For example, a missing DLL exception may actually be a result of an incorrect address/directory attribute in the Windows registry (a common system file corrupted by viruses/application damage).

The Windows registry contains configuration data for all operating system programs including details of all your DLL files. If this has become damaged then it may be report faults to you as DLL issues. At can be repaired as follows:

  • Try running an anti-virus scan: If the key was damaged/corrupted by a bug in your system then a scan will be able to isolate and repair the damage that has been.
  • Try running a registry cleaner: If the registry key was corrupted by application changes then anti-virus software will not be able to detect this. Use a regedit cleaner (e.g. Registry Easy) to automate the repairs for you.

An alternate and free registry fix option which doesn’t involve resorting to third-party applications is to try using the System Restore utility (all programs/accessories/system tools). This application allows you to rollback OS programs, the registry and many DLLs to an earlier date stamped version.

Directly fix missing DLL files and corrupted DLLs

There are a number of ways to fix DLL problems directly relating to faulty/missing files. Here are some suggestions:

  • Install application updates: If the fault relates to a specific program/application then you can fix missing DLL files by reinstalling the application or updating it with a new patch. DLLs change on a regular basis so are regularly included in patch updates and new product versions.
  • Run Windows update: If the DLL is not specific to one particular program or is part of the operating system then try getting the latest OS patch to download and install the latest files. This is something of a long shot however as patch updates will not always include every single OS-related DLL on your hard drive.
  • System File Checker: Users of Windows 2000/XP can also use the system file checker software to fix DLL issues and OS program problems.

The dangers of using a single file download to fix DLL files

The last resort option for fixing DLL problems is to try and download a new version of the file and installing it directly on your hard drive.

  1. The first problem with doing this is that you may get an incorrect version of the file which may cause odd system behavior or other exceptions on your system.
  2. The second problem is that you need to be 100% sure you are using a reputable website to download the files. Always use one of the bigger websites as some hackers have created small download sites purely to make their malware viruses available as DLLs.
