REX Shared Library_x64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like REX Shared Library_x64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like mrt.exe - to follow. These files were created so that multiple programs (eg. FL Studio) could share the same REX Shared Library_x64.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 REX Shared Library_x64.dll is attempted to be loaded either when FL Studio is starting up, or in some cases already running. Some of the most common REX Shared Library_x64.dll errors include:
- Access Violation at address - REX Shared Library_x64.dll.
- REX Shared Library_x64.dll could not be found.
- Cannot find C:\Program Files (x86)\Image-Line\Shared\REX Shared Library_x64.dll.
- Cannot register REX Shared Library_x64.dll.
- Cannot start FL Studio. A required component is missing: REX Shared Library_x64.dll. Please install FL Studio again.
- Failed to load REX Shared Library_x64.dll.
- The application has failed to start because REX Shared Library_x64.dll was not found.
- The file REX Shared Library_x64.dll is missing or corrupt.
- This application failed to start because REX Shared Library_x64.dll was not found. Re-installing the application may fix this problem.
Your REX Shared Library_x64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with FL Studio), or deleted by a malware infection. Furthermore, REX Shared Library_x64.dll file corruption could be caused from a power outage when loading FL Studio, system crash while loading REX Shared Library_x64.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.
