nio.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like nio.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like bypass_client_win32.exe - to follow. These files were created so that multiple programs (eg. Bypass Proxy Client) could share the same nio.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 nio.dll is attempted to be loaded either when Bypass Proxy Client is starting up, or in some cases already running. Some of the most common nio.dll errors include:
- Access Violation at address - nio.dll.
- nio.dll could not be found.
- Cannot find C:\Program Files (x86)\Bypass\Client\_jvm\bin\nio.dll.
- Cannot register nio.dll.
- Cannot start Bypass Proxy Client. A required component is missing: nio.dll. Please install Bypass Proxy Client again.
- Failed to load nio.dll.
- The application has failed to start because nio.dll was not found.
- The file nio.dll is missing or corrupt.
- This application failed to start because nio.dll was not found. Re-installing the application may fix this problem.
Your nio.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Bypass Proxy Client), or deleted by a malware infection. Furthermore, nio.dll file corruption could be caused from a power outage when loading Bypass Proxy Client, system crash while loading nio.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.
