AppInstallerBackgroundTasks.winmd is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AppInstallerBackgroundTasks.winmd, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Cisco VPN Client Fix for Windows 8.1 and 10) could share the same AppInstallerBackgroundTasks.winmd 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 WINMD 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 AppInstallerBackgroundTasks.winmd is attempted to be loaded either when Cisco VPN Client Fix for Windows 8.1 and 10 is starting up, or in some cases already running. Some of the most common AppInstallerBackgroundTasks.winmd errors include:
- Access Violation at address - AppInstallerBackgroundTasks.winmd.
- AppInstallerBackgroundTasks.winmd could not be found.
- Cannot find C:\Program Files\WindowsApps\Microsoft.DesktopAppInstaller_1.0.32912.0_x64__8wekyb3d8bbwe\AppInstallerBackgroundTasks.winmd.
- Cannot register AppInstallerBackgroundTasks.winmd.
- Cannot start Cisco VPN Client Fix for Windows 8.1 and 10. A required component is missing: AppInstallerBackgroundTasks.winmd. Please install Cisco VPN Client Fix for Windows 8.1 and 10 again.
- Failed to load AppInstallerBackgroundTasks.winmd.
- The application has failed to start because AppInstallerBackgroundTasks.winmd was not found.
- The file AppInstallerBackgroundTasks.winmd is missing or corrupt.
- This application failed to start because AppInstallerBackgroundTasks.winmd was not found. Re-installing the application may fix this problem.
Your AppInstallerBackgroundTasks.winmd file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Cisco VPN Client Fix for Windows 8.1 and 10), or deleted by a malware infection. Furthermore, AppInstallerBackgroundTasks.winmd file corruption could be caused from a power outage when loading Cisco VPN Client Fix for Windows 8.1 and 10, system crash while loading AppInstallerBackgroundTasks.winmd, 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.
