Are you suffering from the missing DLL files error when opening your applications? Take it easy. Read this post from MiniTool to see how to fix this issue including how to restore missing DLL files with the best data recovery software.

DLL Missing or Not Found Errors

DLL, short for Dynamic Link Library, refers to a type of file format containing multiple codes and procedures for Windows programs that can call upon to do many things. DLL is helpful to share data and resources, allowing multiple applications to access the contents of a single file at the same time. These libraries usually have DLL file extensions. 

However, sometimes the application is not working due to the trouble of “missing DLL files”.

To be specific, when trying to open an application, you may receive a pop-up message saying a .dll file is missing or not found. Listed below are the common missing DLL file error messages.

  • The program can’t start because the .dll file is missing from your computer. Try reinstalling the program to fix this problem.
  • Cannot find .dll. Please, reinstall this application.
  • This application failed to start because .dll was not found. Reinstalling the application may fix this problem.
  • The code execution cannot proceed because .dll was not found. Reinstalling the program may fix this problem.

Why do the missing or not found DLL errors occur? The common reasons are as follows.

1. Accidentally delete a DLL file.

When trying to clean up space on a hard disk or uninstalling/installing a program, a single DLL file may be deleted mistakenly. 

2. DLL file is overwritten.

A recent installation of a program may overwrite an existing DLL file with an invalid or incompatible DLL file.

3. The DLL file is corrupted.

A bad application installation may corrupt one or more files, causing.dll errors.

In addition, malware infection, hardware malfunction, etc. can cause DLL file errors. What should you do if you find a DLL file is missing or not found? Try the following feasible ways to fix DLL errors.

To get deleted or lost DLL files back, just do the following step-by-step instructions.

Step 1: Double-click MiniTool Power Data Recovery to open it. Usually, the DLL files are regarded as critical system files and saved to C:\Windows\System32. Hence, here we choose the C partition to scan. If the missing DLL file is located in another drive, choose the actual drive to scan.

After that, MiniTool Power Data Recovery will start to scan the partition you selected.

A full scan may take a long time. For best recovery results, we do not recommend stopping the scan midway.

Step 2: In the scan result window, this hard drive recovery service will list all found files. You can quickly locate the target file by using the search box.

Just type the file name or file extension in the search box and press Enter, and the search result will be displayed. For example, if you receive a $RE1PD3S.dll missing error, you can type $RE1PD3S.dll to find this DLL file.

If you cannot remember the specific names of the missing DLL files, you can type .dll in the search box to view all found DLL files.

Step 3: After finding the needed DLL files, check them and click the Save button to choose a location to store them.

Do not store the found DLL files where they were lost. Otherwise, they may be overwritten and become unrecoverable.

Way 5: Undelete DLL Files via System Restore

If the missing DLL files issue is caused by a change that is made to an important file or system configuration, a System Restore can be helpful to repair the DLL files.

Fixing DLL errors via System Restore only works if you have successfully created a system restore point before the problem occurred.

Follow the steps below to restore your system.

Steps vary from different Windows versions, please choose the corresponding options to finish the system restore. Here we take Windows 10 for example.

Open Control Panel using the Windows search box and select Recovery > Open System Restore. Then follow the on-screen instructions or refer to this post Make the Most of System Restore in Windows 10 to complete the necessary actions.

After restoring your system to an earlier state, check whether the missing DLL files problem re-appears.

Way 6: Run a Virus/Malware Scan

In some cases, DLL missing or not found problems are caused by virus infection. Some hostile programs can masquerade as DLL files, bringing damage to your applications. Thus, to fix the DLL errors, you need to download an antivirus tool from the Internet and use it to perform a virus scan and removal. Or you can use Windows built-in antivirus – Windows Defender to scan for viruses or malware.
