libssl9.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libssl9.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like iscsicli.exe - to follow. These files were created so that multiple programs (eg. Acronis Disk Director Home) could share the same libssl9.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 libssl9.dll is attempted to be loaded either when Acronis Disk Director Home is starting up, or in some cases already running. Some of the most common libssl9.dll errors include:
- Access Violation at address - libssl9.dll.
- libssl9.dll could not be found.
- Cannot find C:\Program Files (x86)\Common Files\Acronis\DiskDirector\Common\libssl9.dll.
- Cannot register libssl9.dll.
- Cannot start Acronis Disk Director Home. A required component is missing: libssl9.dll. Please install Acronis Disk Director Home again.
- Failed to load libssl9.dll.
- The application has failed to start because libssl9.dll was not found.
- The file libssl9.dll is missing or corrupt.
- This application failed to start because libssl9.dll was not found. Re-installing the application may fix this problem.
Your libssl9.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Acronis Disk Director Home), or deleted by a malware infection. Furthermore, libssl9.dll file corruption could be caused from a power outage when loading Acronis Disk Director Home, system crash while loading libssl9.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.
