What is dll error?

DLL errors are errors that are caused by the multiple .dll files that are in Windows. These files are called "Dynamic Link Libraries" and store links to functions and files that all the programs on your computer can use. They are very important for the smooth operation of your computer, but they are constantly becoming damaged and corrupted - causing the infamous ".dll error". Fortunately, you can fix this issue quite easily.

If the DLL file is missing, perform the following steps to fix the error:

Recover the DLL file using a file recovery tool

If you have accidentally deleted the DLL file, restore it from your Recycle Bin. If you have already emptied the contents of your Recycle Bin, use an advanced file recovery tool to procure the missing DLL.

Reinstall any recently installed/uninstalled program

Incorrect installation of a program or installation of a corrupt program also causes DLL errors. If you are receiving DLL errors, such as the mfc80.dll error, after you have installed a program then uninstall and reinstall the program.

Similarly, if you start receiving errors soon after you have uninstalled a program, install the program again and then uninstall it using either a reliable third-party uninstaller tool or the built-in Add or Remove Programs utility.

When you use legitimate methods to uninstall programs, you are prompted whether or not you want to remove shared files. When this happens, you must choose to retain the shared files on your computer.

Download the missing file

You can also procure a copy of the missing DLL file by downloading the DLL file from a reliable and trustworthy online DLL Directory.

Besides a missing DLL, a corrupt DLL file may also cause recurring DLL errors. Malware infection is the most common reason behind corrupt DLLs. To rectify DLL errors due to malware infection, run a malware scan on your entire system using advanced and robust antivirus and antispyware tools.

You may also receive errors, such as ntdll.dll errors, if the entries related to DLL files in the Windows registry are corrupt. To repair errors occurring due to registry issues, run a registry scan using an efficient registry cleaning software.
