The occurrence of DLL errors is not an unfamiliar sight on Windows-based computers. A normal Windows computer contains thousands of DLL files and because of their presence in great numbers, DLL errors are quite common.

DLL error messages seldom give any insight to their solution. However, with a little knowledge and precaution you can easily get rid of these stubborn looking PC problems.

In this article, we will look at some useful pointers that you can follow to fix common DLL errors, such as wgalogon.dll and connapi.dll errors. Let’s take a look at examples of common DLL error messages that may appear on your screen.

“Connapi.dll file not found”

“This program failed to load because wgalogon.dll file was not found. Reinstall the program to correct this error”

“The file wgalogon.dll is missing”

DLL errors – Causes and Fixes

Incorrect installation/uninstallation of an application: A faulty program may install corrupt or damaged DLL files on your system, causing DLL error messages to appear. Before installing a new program, ensure that its setup files are not damaged or corrupt. Also, in case you are performing a new installation using an installation CD/DVD ensure that the disk is not scratched or damaged.

Similarly, when performing uninstallation take care not to delete any shared DLL files. Deletion of a shared file will cause missing DLL errors to appear when any other program sends a message to the operating system asking for this particular file. If your shared DLL file gets removed during uninstallation of any program, then promptly install the program again to restore the missing file.

Outdated Driver files: Outdated driver files may also lead to DLL errors. To prevent DLL errors, such as connapi.dll error from occurring due to driver problems, ensure that your driver files are up-do-date with the latest releases. You can do this manually or opt for a third-party driver update tool, which can automatically download and install driver updates for you.

Undo any recent system changes: Alteration to any Windows file, such as wgalogon.dll or kernel32.dll may also cause DLL error messages to appear on your screen. If you suspect that you are receiving a DLL error message after you have made changes to an important Windows file or configuration, then use the System Restore utility to undo these changes. You may also try to restore the missing file from the Windows setup CD Recovery Console.

Malware Infection: Malicious programs, such as viruses, worms, trojans, and spyware deliberately add incorrect codes to DLL files. It is important that you install robust antivirus and antispyware tools on your PC to secure your system against such malicious programs. Also, make sure to schedule regular complete virus and spyware scans of your system. Further, remember to keep the live malware definition update feature enabled so that your protective gear gets regularly updated with the new security releases and definitions.

Keep your registry clean and compact: Lastly, make sure to maintain a healthy and clean system registry. Incorrect or missing DLL registry entries often cause DLL errors. The best way to ensure the good health of your registry is to perform regular registry scans using a robust registry cleaning tool. A good registry cleaner ensures that all incorrect or obsolete entries are flushed out of your registry.

If you are startled to find that your computer is becoming terribly slow as compared to the time when you bought it, you may need to sit down and ponder about the changes that have happened since then.

When you bought your computer, it had very little data and very few applications installed on it. That means there was a large amount of unused space on the hard disk and a lesser burden on system resources. While working on the computer it is most likely that you have added data as well as quite a few applications of your own. Secondly, it is quite unlikely that your computer was infected with any malware when you purchased it and it is quite possible that some unwanted programs have made it onto your system. Both these issues need to be addressed if you want to speed up your computer, reduce the number of errors and get rid of malware. In order to achieve this, you need to first take inventory of all the programs that are residing on your PC and perform a complete uninstall of unnecessary programs.

On a Microsoft Windows-based computer, DLL or Dynamic Library files are used to store executable code modules that can be loaded and linked at runtime when required, and then unloaded when the code is no longer required. DLL files are used both by Windows operating systems and the programs installed on them. DLL files help in efficient use of system resources, especially disk space and system memory.

Causes of DLL Errors

There are hundreds of DLL files on your Windows computer, out of which several are shipped with the operating system and several others are added or updated as you add new software to the system or update the existing software. Due to the large number of DLL files on the system there can be several causes of DLL errors. Some of the common reasons for DLL errors are:

• Outdated and incompatible DLL files
• Missing DLL files
• Buggy and corrupt DLL files
• Conflicting DLL files

When you start encountering DLL errors often on your computer, your system is said to be in DLL hell.
