REDDecoder-x64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like REDDecoder-x64.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. Adobe Photoshop Lightroom) could share the same REDDecoder-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 REDDecoder-x64.dll is attempted to be loaded either when Adobe Photoshop Lightroom is starting up, or in some cases already running. Some of the most common REDDecoder-x64.dll errors include:
- Access Violation at address - REDDecoder-x64.dll.
- REDDecoder-x64.dll could not be found.
- Cannot find C:\Program Files\Adobe\Adobe Lightroom\Helpers\DynamicLinkMediaServer\dynamiclinkmediaserver\1.0\REDDecoder-x64.dll.
- Cannot register REDDecoder-x64.dll.
- Cannot start Adobe Photoshop Lightroom. A required component is missing: REDDecoder-x64.dll. Please install Adobe Photoshop Lightroom again.
- Failed to load REDDecoder-x64.dll.
- The application has failed to start because REDDecoder-x64.dll was not found.
- The file REDDecoder-x64.dll is missing or corrupt.
- This application failed to start because REDDecoder-x64.dll was not found. Re-installing the application may fix this problem.
Your REDDecoder-x64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Adobe Photoshop Lightroom), or deleted by a malware infection. Furthermore, REDDecoder-x64.dll file corruption could be caused from a power outage when loading Adobe Photoshop Lightroom, system crash while loading REDDecoder-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.
