Understanding the Windows DLL Error
Posted by FixErrors on May 28th, 2009DLL files (dynamic-link library) are an integral part of your operating system. Though less evident now with later versions of Windows (such as Windows XP and Windows Vista), DLL files can be the single most annoying scourge someone experiencing DLL errors could possibly be forced to endure. The only consolation that you can offer someone living in DLL hell (see below) is that, at the very least, it’s not Windows 95 they are dealing with.
What is a DLL and What Causes the Windows DLL Error?
Most Windows DLL errors are caused by missing DLL files, corrupt DLL files, or multiple versions of various DLL files (though this has been less of an issue since clean-up methods have been put in place since 2001). Since a DLL file plays an important role in how your computer is run, having an error with one can be a real pain.
A DLL is Microsoft’s implementation of the shared library concept. Not sure what that means? Essentially it means that the information contained with the DLL file can be shared across multiple paths and programs, allowing your computer to multi-task more efficiently and run on a small RAM footprint. DLL files come in a few different extensions: .dll, .ocx (for libraries containing ActiveX controls), and .drv (for legacy system drivers). What’s important to remember is that a DLL file can contain code, data, or resources in any combination.
In older versions of Windows (Windows 3.1 right up to Windows 2000) DLL errors were much more common than in Windows XP/Windows Vista. This is because it was possible to have multiple versions of the same DLL file, causing programs to often reference the wrong one. This resulted in incompatibilities, system crashing, and poor system performance in general. It was aptly nicknamed “DLL hell”, as it could take even an educated person quite a while to determine the source of, and the solution to, the problem.
Resolving the Windows DLL Error
If you have an error repair suite, resolving a DLL error is usually as simple as booting up the program and running it. Most DLL errors are pretty standard in that it’s typically the same DLL files that are corrupt or missing. If your error repair suite is unable to replace or repair the DLL file in question, however, you have online resources available to you:
- http://www.regcure.com – Free registry scan that detects and repairs missing/corrupt .dll files
- http://www.dll-files.com – A comprehensive directory that has been online since 1998. Chances are good that you’ll find your missing DLL file here.
- http://www.windll.com – Another directory of DLL and SYS files for download.
