Protein_x64.4.0.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Protein_x64.4.0.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like ApplicationRegistration.exe - to follow. These files were created so that multiple programs (eg. ACID Pro) could share the same Protein_x64.4.0.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 Protein_x64.4.0.dll is attempted to be loaded either when ACID Pro is starting up, or in some cases already running. Some of the most common Protein_x64.4.0.dll errors include:
- Access Violation at address - Protein_x64.4.0.dll.
- Protein_x64.4.0.dll could not be found.
- Cannot find C:\Program Files\ACID\ACID Pro 9.0\Protein\Protein_x64.4.0.dll.
- Cannot register Protein_x64.4.0.dll.
- Cannot start ACID Pro. A required component is missing: Protein_x64.4.0.dll. Please install ACID Pro again.
- Failed to load Protein_x64.4.0.dll.
- The application has failed to start because Protein_x64.4.0.dll was not found.
- The file Protein_x64.4.0.dll is missing or corrupt.
- This application failed to start because Protein_x64.4.0.dll was not found. Re-installing the application may fix this problem.
Your Protein_x64.4.0.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with ACID Pro), or deleted by a malware infection. Furthermore, Protein_x64.4.0.dll file corruption could be caused from a power outage when loading ACID Pro, system crash while loading Protein_x64.4.0.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.
