Common Troubleshooting Steps for DLL Errors

Dynamic Link Libraries or DLL files comprise executable functions that can be dynamically loaded and used by the Windows operating system and other software on it. There are hundreds of DLL files on your computer and this is the reason why there are several causes of DLL errors. Some of the most common causes of DLL errors on Windows XP are:

  • - A program uninstallation process removed one or more shared DLL files from the system.
  • - When a new program was installed, it overwrote an existing and more recent DLL file version.
  • - One or more hardware devices, such as memory and input/output buses that are controlled with a DLL file is malfunctioning.
  • - There are incorrect or corrupt DLL entries in the registry.
  • - A malware infection has damaged the DLL file your system is trying to access.

Because there are so many different causes of DLL errors, you need to resolve them on the basis of what caused the error in the first place.

Listed below are some of the tasks that you can follow to perform a DLL fix in different situations. (click read more)

Resolving Software Related DLL Errors

If a DLL error occurs soon after you have installed a program, it is quite likely that this new program has overwritten one or more new versions of shared DLL files with an older version. In this case, you may try to resolve the error by installing an update for the software you have installed, if it is available. You may also try to obtain a copy of the new version of the DLL file causing the problem and register it on the system. If nothing works, you may use the System Restore utility to revert your system to the time when you had not installed the new application.

If the error follows a program uninstallation process, then it is recommended that you reinstall this program and uninstall it again. However, this time when you remove the program ensure that you retain all shared DLL files on the system.

Resolving Hardware Related DLL Errors

Hardware related errors occur if either the device you are trying to access is malfunctioning, or the device driver for it is corrupt or damaged. To resolve hardware related errors, you may first try to update the driver of the device that is generating the error. You may also try to completely remove this driver and then reinstall it on the system. If this fails to resolve the error, you may have to check your hardware for physical problems.

Resolving Malware Related DLL Errors

Many DLL errors, such as the rundll error, occur if the application files on your computer are infected with a malicious program, such as a virus or a worm. To fix rundll error and other errors caused due to malware infections, you must update your antivirus and antispyware tools and perform a thorough full system scan of your PC. To prevent future infections, you must regularly update these security tools and schedule periodic full system scans to detect and remove any malicious information that may infiltrate your system.

Resolving Registry Related DLL Errors

If your registry is full of corrupt and invalid entries, especially entries that register DLL files on the system, you are bound to be bombarded with frequent DLL errors. To prevent registry problems from occurring, you must regularly clean and repair your Windows registry. You can do this easily with the help of a registry cleaner tool.
