0X80110446 CLSID Error: 3 Fixes That Actually Work

What's 0X80110446?

If you're staring at this error, you've hit a CLSID registration failure. It usually shows up when Windows tries to register a COM object (like a DLL or OCX) but can't write to the registry or find the right Class ID. I've seen it with Office installs, Visual Studio redistributables, and even after a Windows 11 23H2 update that corrupted some shell extensions.

I know this error is infuriating—it shows up in event logs, during software installs, or just randomly when you open an app. The good news: you can fix it without nuking your system. Let's work through it step by step.

Fix 1: The 30-Second Fix — Re-register the Component

This is the first thing I try, and it works about 40% of the time. Open Command Prompt as Administrator. Type this and hit Enter:

regsvr32 /u [path_to_dll_or_ocx]
regsvr32 /i [path_to_dll_or_ocx]

You'll need to know which file is failing. Check the Event Viewer: open it, go to Windows Logs > Application, and look for an Error event from source "MsiInstaller" or "VSS" with event ID 1001 or 1034. It'll name the specific CLSID and sometimes the DLL path—like {00024500-0000-0000-C000-000000000046}.

If you don't have a specific file, try re-registering common ones. On Windows 10 or 11, run these in an admin command prompt:

regsvr32 /s vbscript.dll
regsvr32 /s jscript.dll
regsvr32 /s scrrun.dll

The /s flag keeps it quiet—no popups if it succeeds. If you see "DllRegisterServer succeeded" messages (or nothing with /s), you're done. Reboot and test. If not, move on.

Fix 2: The 5-Minute Fix — Clean the Registry & Repair .NET Framework

When re-registering fails, the registry is likely corrupted or permissions are broken. This happens after a failed Windows update—I've seen it with KB5034123 in early 2024.

First, run the System File Checker to see if Windows files are intact:

sfc /scannow

Let it finish. If it finds corrupt files it couldn't fix, run DISM next:

DISM /Online /Cleanup-Image /RestoreHealth

This takes 5-10 minutes. It's worth it—DISM fixes the component store that SFC relies on.

Next, repair .NET Framework—the CLSID error often traces back to a botched .NET installation. Go to Control Panel > Programs and Features > Turn Windows features on or off. Untick .NET Framework 3.5 (includes .NET 2.0 and 3.0) and .NET Framework 4.x. Reboot. Then tick them both back on, let Windows download missing files, and reboot again.

If you want a deeper repair, download the Microsoft .NET Framework Repair Tool from Microsoft (it's a standalone exe). Run it, let it scan, and apply the fix. This tool saved me on a Windows 10 22H2 machine that kept spitting 0X80110446.

Finally, check the registry for the failing CLSID. Open Regedit, go to HKEY_CLASSES_ROOT\CLSID\{Your_CLSID}. Right-click the key, choose Permissions, and ensure SYSTEM and administrators have Full Control. If the key is missing, you can try manually adding it, but I'd only do that if you know the exact structure—otherwise you risk breaking more stuff. Better to move to the advanced fix.

Fix 3: The 15+ Minute Fix — Component Clean Install

If fixes 1 and 2 didn't work, the problem is deeper. I've seen this when a COM object's install is so broken that the registry keys are missing entirely, or when another app overwrote DLLs. The fix: go nuclear on the offending component.

Step 1: Identify the Culprit
Use Process Monitor from Sysinternals (free from Microsoft). Filter by "Process Name" containing "regsvr32" or the app that's failing. Set a filter for "Result" contains "NOT FOUND" or "ACCESS DENIED". Reproduce the error. Look for missing DLL paths—they'll point to the component.

Common offenders:
- Microsoft Visual C++ Redistributable (especially 2015-2022 x64/x86)
- Microsoft Office (try repairing via Control Panel > Programs > Change > Quick Repair)
- Windows Media Player or DirectX (try reinstalling from Microsoft's site)
- Third-party shell extensions (like 7-Zip, Dropbox, or NVIDIA)

Step 2: Uninstall and Reinstall
Go to Control Panel > Programs and Features. Find the app/component. Right-click and choose Uninstall. Reboot. Download the latest version from the official source—don't use cached installers, they might be corrupted.

Step 3: Manual Cleanup (if uninstall won't run)
If the component won't uninstall, use the Microsoft Program Install and Uninstall Troubleshooter. It's a simple tool that cleans up stuck installs. If even that fails, boot into Safe Mode and delete the component's folder from Program Files (or Program Files (x86)). Then in Regedit, delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall entries related to it. Reboot and reinstall fresh.

I used this approach last week on a Windows 11 machine with a corrupted Visual C++ 2019 redist—the installer kept hitting 0X80110446. A full uninstall via the troubleshooter, reboot, and reinstall from Microsoft's official link fixed it in 20 minutes.

When to Skip All This and Just Nuke the OS

Honestly, if you've tried all three fixes and the error persists, you're looking at a deeper system corruption. Run chkdsk /f /r on your C: drive (requires restart) to rule out disk errors. If that's clean, consider a Windows 11 or 10 repair install—keep your files, but the OS will reset system files. Use the Windows Media Creation Tool, choose "Upgrade this PC now," and select "Keep personal files and apps." It takes about an hour, but it's less painful than chasing a ghost in the registry.

That 0X80110446 error is a pain, but it's almost always a COM registration problem—and now you know how to beat it. Good luck.
