vmx86ver.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like vmx86ver.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 7za.exe - to follow. These files were created so that multiple programs (eg. VMWare Workstation Player) could share the same vmx86ver.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 vmx86ver.dll is attempted to be loaded either when VMWare Workstation Player is starting up, or in some cases already running. Some of the most common vmx86ver.dll errors include:
- Access Violation at address - vmx86ver.dll.
- vmx86ver.dll could not be found.
- Cannot find C:\Program Files\Common Files\VMware\Drivers\vmx86\Win7\vmx86ver.dll.
- Cannot register vmx86ver.dll.
- Cannot start VMWare Workstation Player. A required component is missing: vmx86ver.dll. Please install VMWare Workstation Player again.
- Failed to load vmx86ver.dll.
- The application has failed to start because vmx86ver.dll was not found.
- The file vmx86ver.dll is missing or corrupt.
- This application failed to start because vmx86ver.dll was not found. Re-installing the application may fix this problem.
Your vmx86ver.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with VMWare Workstation Player), or deleted by a malware infection. Furthermore, vmx86ver.dll file corruption could be caused from a power outage when loading VMWare Workstation Player, system crash while loading vmx86ver.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.
