libvoip_x86.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libvoip_x86.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. ICQ) could share the same libvoip_x86.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when libvoip_x86.dll is attempted to be loaded either when ICQ is starting up, or in some cases already running. Some of the most common libvoip_x86.dll errors include:
- Access Violation at address - libvoip_x86.dll.
- libvoip_x86.dll could not be found.
- Cannot find C:\Users\Tester\AppData\Roaming\ICQ\bin\libvoip_x86.dll.
- Cannot register libvoip_x86.dll.
- Cannot start ICQ. A required component is missing: libvoip_x86.dll. Please install ICQ again.
- Failed to load libvoip_x86.dll.
- The application has failed to start because libvoip_x86.dll was not found.
- The file libvoip_x86.dll is missing or corrupt.
- This application failed to start because libvoip_x86.dll was not found. Re-installing the application may fix this problem.
Your libvoip_x86.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with ICQ), or deleted by a malware infection. Furthermore, libvoip_x86.dll file corruption could be caused from a power outage when loading ICQ, system crash while loading libvoip_x86.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
