msrating.dll Errors: Rebuild the Windows Component Safely

If Windows reports that msrating.dll is missing, msrating.dll was not found, or that the code execution cannot proceed because it was not found, the affected program will usually refuse to start. An error stating that msrating.dll could not be loaded or is not designed for Windows points to a damaged, mismatched or unavailable Windows component.

The 60-second answer

msrating.dll is a genuine Microsoft file called Internet Ratings and Local User Management DLL. It belongs to the Internet Explorer and Windows Internet Ratings subsystem, not to Visual C++, DirectX, .NET or a graphics driver.

Do not download a replacement from a DLL website. There is no legitimate standalone msrating.dll redistributable. The safest repair path is:

1. Install pending Windows updates and restart.
2. Run DISM, then System File Checker.
3. Repair or reinstall the one affected application if Windows itself appears healthy.
4. Check antivirus quarantine and the file’s location.
5. Use Windows recovery options if component servicing remains damaged.

Microsoft continues to service this file through Internet Explorer cumulative updates, even though Internet Explorer itself is no longer supported as a modern browser. Microsoft’s update documentation lists msrating.dll among the files included in these updates. (Microsoft Internet Explorer cumulative update)

What causes an msrating.dll error

The correct fix depends on where the failure occurs.

Older software may request msrating.dll even if you never open Internet Explorer. Applications can load Windows and Internet Explorer libraries indirectly, particularly when they use legacy web, content-rating or user-management components.

The file may be present on Windows 7, Windows 8.1 and Windows 10 installations because it was historically delivered with Internet Explorer and Windows servicing. Its presence on a current Windows installation depends on the edition, servicing state and installed legacy components. Internet Explorer 11 has reached the end of support, so reinstalling Internet Explorer is not the normal solution. (Microsoft Internet Explorer Downloads)

Fix 1: Install Windows updates first

Because msrating.dll is serviced as part of Windows and Internet Explorer components, Windows Update is the safest first repair.

Windows 11

1. Open Start > Settings.
2. Select Windows Update.
3. Select Check for updates.
4. Install every applicable update.
5. Restart when Windows requests it.
6. Open the affected program again.

Windows 10

1. Open Start > Settings.
2. Select Update & Security.
3. Select Windows Update.
4. Choose Check for updates.
5. Install the available updates and restart.

If an update repeatedly fails, note its error code and continue with the DISM and SFC procedure below. Do not search for an individual msrating.dll version that matches a number shown on a third-party site. Exact file versions vary with Windows release, architecture, servicing branch and installed updates.

Fix 2: Repair Windows with DISM and SFC

Use an elevated Command Prompt. Microsoft recommends running DISM before SFC because DISM repairs the Windows component store that SFC uses as a source.

1. Open Start.
2. Type Command Prompt.
3. Right-click Command Prompt.
4. Select Run as administrator.
5. Approve the User Account Control prompt.
6. Run this command:

DISM.exe /Online /Cleanup-Image /RestoreHealth

Wait for it to finish. Do not close the window if progress appears to pause.

When DISM completes, run:

sfc /scannow

Wait until verification reaches 100 percent. Then restart Windows and test the affected program.

Possible SFC results include:

• Windows Resource Protection did not find any integrity violations: protected system files were not damaged. Continue with application repair and dependency checks.
• Windows Resource Protection found corrupt files and successfully repaired them: restart and test the program.
• Windows Resource Protection found corrupt files but was unable to fix some of them: run DISM again, restart, and repeat SFC. If corruption remains, use a matching repair source or Windows recovery.

For a repair source, Microsoft documents this form:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

C:RepairSourceWindows is only an example. Replace it with a genuine Windows installation source matching your installed edition and build. (Microsoft repair instructions)

Repeatedly hunting through Windows folders and rerunning SFC or DISM can make it difficult to tell what actually changed. Outbyte PC Repair can scan for reported system problems and show what needs attention; repair actions are handled by the full version. It is optional, and repairing the affected application remains the definitive fix when that application is the damaged part.

Fix 3: Repair the affected application

If only one program reports the error and Windows continues to operate normally, the application installation may be damaged. Do not place a downloaded copy of msrating.dll beside the program’s executable.

Windows 11 Store and desktop applications

1. Open Start > Settings.
2. Select Apps > Installed apps.
3. Find the affected program.
4. Select the three-dot menu beside it.
5. Choose Advanced options.
6. Select Repair if available.
7. Start the program again.

The Repair option is not available for every application. For traditional desktop software:

1. Open Control Panel.
2. Select Programs > Programs and Features.
3. Right-click the affected program.
4. Choose Repair or Change.
5. Follow the installer’s instructions.
6. Restart Windows if requested.

If repair fails, uninstall the application and reinstall it from the publisher’s official installer. Back up application data or saved games first. Microsoft also documents these repair paths and notes that available options vary by program. (Microsoft repair apps and programs)

For a game, open its official launcher and use Verify, Verify integrity, Scan and repair or the equivalent command. The exact menu depends on the launcher. Verification is preferable to copying a DLL into the game directory because it checks the application’s own files without masking a Windows component problem.

Fix 4: Check antivirus quarantine

If the file disappeared recently, security software may have quarantined it. Do not restore it automatically merely because a program says it is missing.

In Windows Security:

1. Open Start > Settings.
2. Select Privacy & security > Windows Security.
3. Select Virus & threat protection.
4. Choose Protection history.
5. Review detections involving msrating.dll.
6. Check the reported file path, detection name and action taken.

Restore a quarantined file only after confirming that it was in a normal Windows component directory and has a valid Microsoft digital signature. If the file was in a random download folder, a user-writable directory or an unexpected application folder, leave it quarantined and run a full security scan.

Protection History entries are retained for a limited period, so an old quarantine event may no longer be visible. (Microsoft Protection History)

Fix 5: Check the file location and architecture

On a 64-bit Windows installation, the normal locations are:

• Native 64-bit copy: %WINDIR%System32msrating.dll
• 32-bit copy: %WINDIR%SysWOW64msrating.dll

The names are counterintuitive. In 64-bit Windows, System32 contains native 64-bit system files, while SysWOW64 contains 32-bit files used by 32-bit applications. This behavior is part of Microsoft’s WOW64 file-system redirection. (Microsoft File System Redirector)

To inspect a file:

1. Press Windows key + R.
2. Enter %WINDIR%System32.
3. Press Enter.
4. Search for msrating.dll.
5. Right-click it and select Properties.
6. Check the Digital Signatures tab and the Details tab.

A file in the expected Windows directory with Microsoft listed as its signer is more trustworthy than one in a random application folder. Do not swap files between System32, SysWOW64 and an application directory.

A 32-bit application may need the 32-bit Windows copy, while a 64-bit application needs the native copy. A message saying the file is “not designed to run on Windows” can indicate architecture mismatch, corruption or a damaged dependency. It does not prove that the file itself is malicious.

Fix 6: Do not use regsvr32 for this error

regsvr32 is intended for DLLs that expose registration entry points such as DllRegisterServer. It is not a general-purpose repair command.

Running this command:

regsvr32 msrating.dll

will commonly produce a load or entry-point error and will not restore a missing Windows payload. There is no evidence that ordinary msrating.dll missing-file errors require registration. (Microsoft regsvr32 documentation)

Do not use regsvr32 unless the official documentation for the specific application explicitly requires that registration step.

Fix 7: Treat driver updates as unrelated unless evidence points there

msrating.dll is not a graphics, audio, printer or chipset driver component. Updating drivers is therefore not a justified first response to this particular error. Device Manager is useful only if the same application also reports a separate hardware or device problem.

To check for a related device issue:

1. Right-click Start.
2. Select Device Manager.
3. Look for a yellow warning icon.
4. Expand the relevant device category.
5. Right-click the affected device.
6. Select Properties and review the General and Driver tabs.
7. Use Update driver only when the device itself is reporting a problem.

Manually identifying stale drivers across many device categories is separate from repairing msrating.dll. Outbyte Driver Updater can scan and identify driver updates, with installation handled by the full version; it is optional and does not replace Windows component repair or application reinstallation.

Fix 8: Use recovery options if servicing is damaged

If DISM and SFC cannot repair Windows, use a matching repair source, System Restore or another Windows recovery option.

System Restore can roll system files and settings back to an earlier restore point without removing personal files. It is useful when the error began immediately after an update or software installation. Open Start, search for Create a restore point, select System Restore, and choose a restore point from before the failure. (Microsoft recovery options)

On supported Windows 11 installations, another option is:

1. Open Settings.
2. Select System > Recovery.
3. Find Fix problems using Windows Update.
4. Select Reinstall now if available.
5. Follow the prompts.

This reinstalls the current Windows version while preserving apps, files and settings when the option is offered. (Microsoft Windows repair reinstall)

Why downloading msrating.dll is unsafe

Random DLL download sites can provide:

• The wrong Windows build
• The wrong 32-bit or 64-bit architecture
• A modified or malicious file
• A file with incompatible dependencies
• A copy that hides rather than repairs the component-store problem

Copying that file into an application directory can also change DLL search behavior and create another security or compatibility problem. Use Windows Update, DISM, SFC and the official installer for the affected application instead.

FAQ

Is msrating.dll a Microsoft file?

Yes. Its description is Internet Ratings and Local User Management DLL, and it is associated with Microsoft’s Internet Explorer and Windows components. Microsoft-serviced Internet Explorer updates include the file.

Does Windows 11 always contain msrating.dll?

Not necessarily. Component presence depends on the Windows edition, servicing state and installed legacy compatibility components. Do not treat an absent file as proof that you should download one manually.

Should I install Visual C++, DirectX or .NET?

Not as a first response. There is no evidence that those runtimes specifically provide msrating.dll. Repair Windows or the single affected application based on where the error occurs.

Should I reinstall Internet Explorer?

No. Internet Explorer has reached the end of support. Use Windows servicing, applicable updates and recovery options instead of trying to reinstall the browser.

What if SFC says it repaired the file but the program still fails?

The displayed DLL may be the first dependency that failed, not the only problem. Repair the application, inspect its logs and verify its files. Also check whether the program is 32-bit and whether it is trying to load a private copy from its own folder.

Is it safe to restore msrating.dll from antivirus quarantine?

Only after checking its original path, Microsoft digital signature and detection details. If the file was unsigned or located outside the expected Windows component directories, leave it quarantined and investigate further.
