Causes Of DLL Errors



The dynamic link library or DLL file is a type of ‘library’ harboring executable functions and codes for use in the Windows family of operating systems.

DLL files are known for their use across different applications at a time. Other types of DLL files are specifically created for use by one or a few programs. These specific DLL files are usually only loaded upon running its correlating program.

Even though DLL files sound relatively simple in use, they’re actually a source of many problems within the Windows operating system family.

Windows is especially prone to generating errors from DLL files—to the point that they’re usually the main source of errors in Windows. Here, we’re going to look at the most common sources of DLL errors in Windows.

Don’t forget: never download DLL files from the Internet when repairing missing and/or corrupted DLL files. These files can contain malicious DLL files that can cause further damage to your system.


Common causes of DLL errors in Windows

DLL errors are so common that they’re considered the ‘bane’ of many Windows fix-it experts everywhere. Why? Here are the causes behind the disdain.


Common Cause #1: Newly installed applications that replace up-to-date DLL files with a previous version. 

Sometimes, installing a program can overwrite current DLL files with older ones. This commonly happens when installing completely new software to a Windows computer. When this happens, programs that share that specific DLL file will start experiencing errors, due to the ‘new’ file lacking the necessary data to execute.

Fix? This is usually a problem can be avoided by the developers, who now take care to ensure all associated DLL files either use existing DLL files within Windows or updated files via the software itself.


Common Cause #2: Malfunctioning or faulty hardware that can corrupt files when in use. 

Malfunctioning and/or faulty hardware, commonly hard drives, can actually corrupt files when in use. This happens when the faulty hard drives operate and corrupt files if in use. Sometimes, malfunctioning computer memory can also corrupt DLL files; on other occasions, the registry and its DLL files can corrupt due to misbehaving applications or software.

Fix? The best solution involves getting a new hard drive, computer memory and/or entirely reinstalling Windows.


Common Cause #3: Infestations from malicious adware, spyware, malware and/or computer viruses. 

The most common cause of corrupted DLL files is computer infestations by the aforementioned. These programs can ‘worm’ their way into the Windows registry and corrupt or completely replace existing DLL files. When this happens, Windows becomes much more prone to DLL errors and may even stop properly working.

Fix? Using a malware scanner and/or anti-virus program works best to remove corrupted DLL files and other harmful files. Sometimes, severe infestations require an entirely fresh reinstall of Windows.
