What are BCUnRAR.dll Error Messages?

Dynamic Link Library BCUnRAR.dll Errors

BCUnRAR.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like BCUnRAR.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Beyond Compare) could share the same BCUnRAR.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 BCUnRAR.dll is attempted to be loaded either when Beyond Compare is starting up, or in some cases already running. Some of the most common BCUnRAR.dll errors include:

Access Violation at address - BCUnRAR.dll.
BCUnRAR.dll could not be found.
Cannot find C:\Program Files\Beyond Compare 4\BCUnRAR.dll.
Cannot register BCUnRAR.dll.
Cannot start Beyond Compare. A required component is missing: BCUnRAR.dll. Please install Beyond Compare again.
Failed to load BCUnRAR.dll.
The application has failed to start because BCUnRAR.dll was not found.
The file BCUnRAR.dll is missing or corrupt.
This application failed to start because BCUnRAR.dll was not found. Re-installing the application may fix this problem.

Your BCUnRAR.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Beyond Compare), or deleted by a malware infection. Furthermore, BCUnRAR.dll file corruption could be caused from a power outage when loading Beyond Compare, system crash while loading BCUnRAR.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.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many BCUnRAR.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
