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