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Outdated Driver files: Outdated driver files may also lead to DLL errors.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.
