How to Download Missing DLL Files

A Dynamic Link Library (DLL) is a type of file used by the Windows operating system and third-party programs to share functions. Windows includes a large number of vital system DLLs by default. Developers also create their own DLLs and bundle them with their software.

We all face the dreaded missing DLL error from time to time. When you open a program, only for it to crash immediately!

To solve this, let’s take a closer look at what DLLs do, how to locate and download missing DLL files, and the best way to keep Windows running smoothly. 

What are DLL files?

DLL files add functionality to Windows programs by supplying extra code and data. When a program needs to use a specific feature, it loads the appropriate DLL file from the system into memory. This is different from static linking, where all of the code is compiled into a single, self-contained executable file.

Developers know they can make their software more efficient by relying on existing DLLs. Moreover, because many DLLs are shared by multiple programs, it reduces the amount of total memory used by your computer.

However, when a DLL file mysteriously goes missing, the software that uses it may not function at all. Even worse, multiple programs can be affected due to their shared nature.

Typically, the program will produce an error on launch, saying the DLL was not found, and then crash after clicking the ‘ok’ button. Other times, crashing occurs mid-task. Some system DLLs are even required for Windows to boot.

Why do DLLs go missing?

Windows DLLs can go missing for various reasons. You might accidentally delete DLL files yourself, though this is rare. Most important system DLLs are stored in the obscure System32 or SysWOW64 folders on the Windows operating system and are rarely accessed by users.

Viruses and malware

A more common cause is when your system is infected by malware and viruses that can wreak havoc and delete these files without your knowledge.

By using award-winning antivirus Avira as its base, Fortect scans for potentially dangerous software and damage caused by malware. This enables it to repair your system if DLLs are:

• Deleted by viruses and malware.
• Corrupted by viruses and malware.
• Prevented from access because the Windows file system has been disrupted.

Software installation errors

If you interrupt the installation of a new program before it’s complete, this can prevent a DLL from installing. Moreover, corrupted, or poorly written software updates can remove or replace DLLs and cause problems for other programs.

Some software suggests that you update other tools during the installation process. Many people skip these options, assuming everything is already up to date and can overlook an important DLL required to run the program.

Windows installation errors 

Even the operating system itself can be the culprit if it is never installed properly or recent Windows updates fail.

A Fortect scan can quickly determine if your Windows installation is incomplete and a potential cause for DLL issues. This compares how the system should look with how yours looks at the moment.

Hardware failure

Hardware failure can also damage the DLL library. If your hard drive is on its last legs, sectors that store DLLs can go bad and prevent programs from accessing what they need to run.

In this case, it’s best to salvage what is still accessible on the hard drive and replace it as quickly as possible. A fresh Windows installation may be needed if it’s your main drive.

How to find missing DLL files?

To resolve missing DLL errors, it is usually necessary to replace the missing DLL file or reinstall the software that depends on it.

But, where can you search for missing DLL files? It’s common to turn to Google and simply enter the file’s name as Windows presents it in its error message. 

Manually search for missing DLLs

Manually searching is a reasonable approach, however not all DLL archival sites are legitimate, and many contain intrusive ads and fake download links. Therefore, it’s important to research reputable sites before trying to find the file yourself.

Even then it can take more time and hassle than it’s worth. Here’s where Fortect comes into play!

Using Fortect to find missing DLLs

Fortect can do all the hard work for you with its comprehensive system scan and repair features. It detects which DLLs are missing.

Then, rather than searching yourself, Fortect draws from its regularly updated database of files to find the latest working versions for you.

Windows DLLs can be replaced if they are: 

• Missing 
• Corrupt
• Damaged or deleted by malware

How to download a DLL file?

You have two options to download a missing DLL file – manually or via a DLL fixer like Fortect.

Manually download a DLL file

To download a DLL file, you will need to find a legitimate copy online and save it to your computer or laptop.

• If it comes zipped, right-click, then extract the contents.

All you need is the appropriate file name with the .dll extension. This will be the same as the name given during the Windows error.

• Beware of other bundled junk that can sometimes be included in manual DLL downloads.

How to download a DLL file with Fortect?

Missing DLL files are easily found by Fortect and downloaded automatically when you proceed with the repair option. Sit tight and wait for the process to complete and the DLL will now be back on your system.

How to install a DLL file?

DLL files can be installed manually by putting them in the right folder or automatically using Fortect’s repair function. You cannot run a DLL file on its own.

Installing DLL files manually

First, determine where the DLL file needs to be installed. For most standard Windows DLLs these are the System32 or SysWOW64 folders. 

The System32 folder contains 64-bit DLLs, while the SysWOW64 folder contains 32-bit DLLs.

• The System32 folder is located at C:\Windows\System32
• The SysWOW64 folder is located at C:\Windows\SysWOW64

However, it’s important to note that some DLL files may be located in other folders or directories as well, depending on third-party software. For example, some video games store DLLs in their installation directories.

Installing DLL files with Fortect

When Fortect detects missing Windows DLL files and you proceed with the repair process, it will install these automatically in the required Windows folders. Here is how to do it:

1. Download and Install Fortect on your PC
2. Launch the tool and Start scanning
3. Fortect will find DLL files that could be causing PC problems (missing, corrupted, or simply old)
4. Click on Start Repair (after product activation) to start replacing problematic DLLs with working versions

Note: Fortect cannot repair or replace DLL files that belong solely to third-party programs. I.e., that are not shared in the registry. In these cases, the best course of action is to try reinstalling the software or locating the DLL and installing it manually to its correct folder as outlined above.

How to check if the DLL file is working?

Unless you are a developer using a DLL viewer, checking whether a DLL file is working correctly is as simple as opening the program and carrying out your desired tasks. You cannot open or view a DLL by itself. Most missing or corrupt DLLs will present as a very clear error.

If you have downloaded a DLL manually and placed it in the correct folder, yet the program crashes, it may be outdated, incompatible, or fake. In this case, you can try another source for the file or reinstall the program. It is always wise to restart your computer after installing a DLL or reinstalling a program.
