What are msacm32.drv.mui Error Messages?

Dynamic Link Library msacm32.drv.mui Errors

msacm32.drv.mui is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like msacm32.drv.mui, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 3DViewer.ResourceResolver.exe - to follow. These files were created so that multiple programs (eg. Windows) could share the same msacm32.drv.mui 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 MUI 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 msacm32.drv.mui is attempted to be loaded either when Windows is starting up, or in some cases already running. Some of the most common msacm32.drv.mui errors include:

Access Violation at address - msacm32.drv.mui.
msacm32.drv.mui could not be found.
Cannot find C:\Windows\System32\en-US\msacm32.drv.mui.
Cannot register msacm32.drv.mui.
Cannot start Windows. A required component is missing: msacm32.drv.mui. Please install Windows again.
Failed to load msacm32.drv.mui.
The application has failed to start because msacm32.drv.mui was not found.
The file msacm32.drv.mui is missing or corrupt.
This application failed to start because msacm32.drv.mui was not found. Re-installing the application may fix this problem.

Your msacm32.drv.mui file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows), or deleted by a malware infection. Furthermore, msacm32.drv.mui file corruption could be caused from a power outage when loading Windows, system crash while loading msacm32.drv.mui, 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 msacm32.drv.mui 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 msacm32.drv.mui 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.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
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 msacm32.drv.mui error, please proceed to the Step 2 below.

Step 2: Run SFC (System File Checker) to restore the corrupt or missing msacm32.drv.mui file.

System File Checker is a utility included with every Windows version that allows you scan and restore corrupted system files. Use the SFC tool to fix missing or corrupt msacm32.drv.mui files (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "cmd" but DO NOT PRESS "ENTER".
Press and hold "CTRL-Shift" on your keyboard while pressing "ENTER".
You'll be prompted with a permission dialog box.
In the box, click "YES".
You should have a black screen with a blinking cursor.
In that black screen, type "sfc /scannow" and hit "ENTER".
SFC will begin scanning for msacm32.drv.mui issues and any other system file problems.
Follow any on-screen commands to complete the process.

Please be aware that this scan might take a while, so please be patient while it is working.

If this Step 2 fails as well, please proceed to the Step 3 below.

sfc /scannow

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 msacm32.drv.mui 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 msacm32.drv.mui error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

Click the appropriate "Download Now" button and download your Windows file version.
Copy the file into the appropriate directory for your Windows version:

Windows Vista: C:\Windows\System32\en-US\
Windows Vista: C:\Windows\SysWOW64\en-US\
Windows 7: C:\Windows\System32\en-US\
Windows 7: C:\Windows\SysWOW64\en-US\
Windows 8: C:\Windows\System32\en-US\
Show 2 more directories +

Windows 8.1: C:\Windows\System32\en-US\
Windows 10: C:\Windows\System32\en-US\

Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve msacm32.drv.mui problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.

Download msacm32.drv.mui Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying msacm32.drv.mui to your appropriate Windows system directory. Microsoft typically does not release Windows MUI files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing msacm32.drv.mui and all other MUI files for Windows. An incorrectly installed MUI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
