DLL Errors and Fixes


Critical DLL or Dynamic Link Library files are a group of small programs. They’re often invoked by various executable (EXE) programs in the Windows operating system to perform certain tasks. Additionally, several programs can use the same DLL file to perform similar operations.

Causes of DLL Errors

Windows operating systems use hundreds of DLL files, and it’s quite likely that you come across a DLL error once in a while. Some DLL errors are not easy to troubleshoot, however if you take a systematic approach, you can fix quite a few of them on your own.

Some of the most common DLL errors include:

  • Missing or corrupt DLL errors due to problems with essential Windows files.
  • Incorrect memory usage errors due to corrupt or buggy DLL files of the software you are using.
  • Deletion of a required shared DLL file.
  • Defective hard drive.
  • Malfunctioning hardware.
  • Virus and spyware infections.
  • Invalid DLL entries in the registry.
  • Overwriting a new DLL file with an older version

DLL Error Fixes

Fixing DLL errors is obviously based on the type of DLL error that you have encountered. Broadly, you can categorize the causes of DLL errors as errors caused due to application problems, errors caused due to virus or spyware infections, and errors due to hardware and driver issues.

For application-related DLL errors, restoring the original DLL file either by reinstalling the application or by applying a patch generally solves problem. You can even try the System Restore utility in Windows to revert system settings to the time when your PC was free from any type of error. For example, you may come across DLL errors wherein your computer displays “antifr.dll not found” or “picsdk.dll not found” errors. Antifr.dll is generally installed with the program ‘PC Guard’, which is a security software. Then again, picsdk.dll is a file belonging to Epson’s ‘Easy Print Module’. To fix both these problems, you need to extract the DLL files from the installation disk of the respective software and copy them to their respective program folders. If this does not work, you may need to reinstall the software to resolve the issue.

For malware related problems, scanning your computer with antivirus and antispyware programs may help you eliminate them from your computer.

You may also use a PC diagnostics tool to run checks on your computer to ensure you don’t have any malfunctioning hardware on the system. For drivers, it is recommended that you use a reliable driver scanner tool to run tests to ensure that all your drivers are healthy, compatible and up-to-date.

However, if your computer regularly encounters DLL errors such as incompatible DLL’s, missing DLLs and DLL conflicts, your computer probably has entered DLL hell and one of the best solutions for this problem is usually reinstalling your Windows operating system.

DLL Error Prevention

As a vigilant user, you can perform a few tasks to prevent DLL errors on your computer. These include:

  • Avoid deleting shared DLL files while uninstalling applications
  • Stay away from installing unknown software applications.
  • Update your Windows operating system and application software on a regular basis.
  • Use registry cleaners and antivirus programs frequently to ensure that your computer is free from DLL errors and other problems.
