DLL errors may occur whenever you install or install any software or you run into hardware or system problem.DLL error may destabilize your PC and may eve cause frequent reboots or sometimes, you may even find it difficult to boot your PC.
What are DLLs?
DLLs or Dynamic Link Libraries are files that are used to store executable functions and code libraries that can be dynamically called, loaded, and run by your Windows operating system and various software programs installed on it to perform specific operations. Because a single DLL file can be shared between several Windows applications, it minimizes the need to add the same code in different applications again and again. For instance, Kernel 32.dll is a core Windows operating system DLL file that carries out operations such as I/O function and memory management. In the same way, Rundll.exe (16-bit) and Rundll32.exe (32-bit) are used to invoke functions exported from DLLs.
When is your PC said to be in DLL Hell?
There are several DLL files on a Windows computer. Many of these files belong to the core operating system and many come along later when you start installing various applications and tools on your computer.
Due to the existence of such a huge number of DLL files on the system, the chances of DLL errors are quite high. And, once DLL errors become a common affair on your computer, the system is said to be in DLL hell.
Most of the DLL errors you encounter are related to:
- Corrupt or missing DLLs
- Conflicting DLLs
- Inaccessible DLLs
- Incompatible DLLs
Causes of DLL Errors
- Removal of shared DLL files when a software program is uninstalled.
- Overwritten DLLs or the addition of outdated or faulty DLLs when new programs are installedâthis usually occurs when you install an old version of a program or when you install faulty or buggy programs.
- Hardware problems, such as low disk space, malfunctioning components, such as motherboard and memory chips, device driver problems, and incorrect or outdated BIOS.
- System problems, such as damaged or missing system folders, corrupt registry hive, and damaged or corrupt DLL files.
- Software problems, such as poorly installed software programs, virus infections, and corrupt program files.
How to fix Dll Errors?
Windows XP DLL errors are resolved depending on what caused the error.
To repair DLL errors caused due to removal of one or more shared DLL files when a program is uninstalled, reinstall the program and uninstall it again. However, this time when prompted whether you want to keep or remove the shared DLL files, choose to retain them on the system.
DLL errors that occur due to overwriting of an existing DLL file by an older version when an application is installed is usually a bit more complicated to fix. If this happens, the first thing that you must try to check is if an update for this new software is available or not. If an update is available, then you may be able to resolve the error by updating the program. Otherwise, you can try to download the overwritten file from the Internet or from some other computer to your system to resolve the error. If you still cannot resolve the problem, you may have to perform a system restore to revert your system back to the time when you had still not installed this program on the system.
Hardware related problems usually occur due to problems with device drivers or malfunctioning hardware. This is the reason why, if an error occurs soon after you install a driver, a driver update, or install a new hardware on the system, you must check them for any problems. You can resolve problems related to device drivers by using the Device Manager utility.
To resolve and prevent problems due to malware programs such as virus and spyware, you must install antivirus and antispyware programs on your computer. You must keep these programs updated with the latest virus definitions and run full system scans at regular intervals to ensure that your system stays free of the latest security threats.
Finally, to prevent and repair DLL errors due to registry problems, it is recommended that you use a good registry cleaner tool to perform regular registry scan and repair. You can also use a registry cleaner tool to perform a customized search for and repair only DLL errors.
