What are mv91xxm.dll Error Messages?

Dynamic Link Library mv91xxm.dll Errors

mv91xxm.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mv91xxm.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. EaseUS Disk Copy) could share the same mv91xxm.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 mv91xxm.dll is attempted to be loaded either when EaseUS Disk Copy is starting up, or in some cases already running. Some of the most common mv91xxm.dll errors include:

Access Violation at address - mv91xxm.dll.
mv91xxm.dll could not be found.
Cannot find C:\Program Files (x86)\EaseUS\Disk Copy\BUILDPE\x86\Drivers\RAID\MARVELL\mv91xxm.dll.
Cannot register mv91xxm.dll.
Cannot start EaseUS Disk Copy. A required component is missing: mv91xxm.dll. Please install EaseUS Disk Copy again.
Failed to load mv91xxm.dll.
The application has failed to start because mv91xxm.dll was not found.
The file mv91xxm.dll is missing or corrupt.
This application failed to start because mv91xxm.dll was not found. Re-installing the application may fix this problem.

Your mv91xxm.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with EaseUS Disk Copy), or deleted by a malware infection. Furthermore, mv91xxm.dll file corruption could be caused from a power outage when loading EaseUS Disk Copy, system crash while loading mv91xxm.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.

How to Fix mv91xxm.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your mv91xxm.dll issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the mv91xxm.dll error, please proceed to the Step 2 below.

Step 2: If recently installed EaseUS Disk Copy (or related software), uninstall then try reinstalling EaseUS Disk Copy software.

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 mv91xxm.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".
After the update is completed, restart your PC.

If Windows Update failed to resolve the mv91xxm.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If Those Steps Fail: Download and Replace Your mv91xxm.dll File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate mv91xxm.dll file version. We maintain a comprehensive database of 100% malware-free mv91xxm.dll files for every applicable version of EaseUS Disk Copy. Please follow the steps below to download and properly replace you file:

Windows 10: C:\Program Files (x86)\EaseUS\Todo Backup\BUILDPE\x86\Drivers\RAID\MARVELL\
Restart your computer.

If you are not currently backing up your data, you need to do so immediately.
