What wldlog.dll is and where it belongs
wldlog.dll is associated with Windows Live Desktop Logging, a shared component of the legacy Windows Live Essentials family. It has been associated with Windows Live Mail, Windows Live Messenger, Windows Movie Maker, and Windows Photo Gallery. Microsoft support discussions show the file in locations such as:
C:Program FilesWindows LiveSharedwldlog.dll
C:Program Files (x86)Windows LiveSharedwldlog.dll
See Microsoft’s records for the Windows Live shared files, Windows Live Mail loaded modules, and Movie Maker and Photo Gallery file paths.

This is an application DLL, not a normal Windows operating-system DLL. It should normally remain with the Windows Live installation and should not be copied into:
C:WindowsSystem32
C:WindowsSysWOW64
A 64-bit version of Windows may still use the 32-bit Windows Live files under Program Files (x86). Do not download a 64-bit replacement simply because Windows itself is 64-bit.
Fix 1: Repair Windows Live Essentials
Repairing the parent application is the safest and most likely solution because it restores the DLL together with the files and dependencies that belong to the same Windows Live release.

Microsoft’s archived Windows Live Essentials release notes describe repairing Windows Live programs through Programs and Features.
How to tell whether repair worked
The affected application should open without the missing-file message. You can also check whether the shared directory now contains wldlog.dll. The exact path depends on whether the Windows Live application was installed under Program Files or Program Files (x86).
If repair fails, restart Windows and repeat the process. If the Windows Live entry is present but the repair option is unavailable, uninstall the damaged suite only after backing up application data, then reinstall the required component from trusted original installation media.
Fix 2: Check whether the file is in the shared folder
Windows Live applications use common files. In some older installations, wldlog.dll is placed in:
C:Program FilesWindows LiveShared
or:
C:Program Files (x86)Windows LiveShared
The affected application may nevertheless report that the file is missing because its installation is damaged or because it is looking in its own program directory.
Check the shared folder as follows:
- Open File Explorer.
- Browse to
C:Program FilesWindows LiveShared. - If it is not there, check
C:Program Files (x86)Windows LiveShared. - Search for
wldlog.dll. - Right-click the file, select Properties, and review its Digital Signatures tab if one is available.
- Confirm that the file came from the same Windows Live installation as the affected application.
Microsoft community guidance has documented copying the shared file into the affected Windows Live application directory, particularly for Photo Gallery. This is a legacy-installation workaround, not a universal repair.
Only consider that workaround when the file is already present, belongs to the same installation, and is valid or came from known original installation media. Copy it only to the application’s own directory. Do not place it in System32 or SysWOW64.
If the application still cannot start after the file is present, the message may refer to a missing dependency. “The specified module could not be found” does not always mean that wldlog.dll itself is absent.
Fix 3: Reinstall the complete Windows Live component
A partial installation can leave files such as wldcore.dll and wldlog.dll in the shared folder while the main application remains unable to load them. This commonly follows an interrupted uninstall, an old offline installer, or mixing files from different Windows Live releases.
- Open Control Panel → Programs → Programs and Features.
- Select the Windows Live or Windows Essentials entry.
- Choose Uninstall/Change.
- Remove the damaged Windows Live component after backing up its data.
- Restart the computer.
- Run the original installer you already trust, using Run as administrator.
- Install the complete application and its shared components.
- Restart Windows again and test it.
Do not mix Windows Live Essentials releases casually. A DLL from one release may not match the application, configuration, or dependencies from another.
Microsoft states that Windows Essentials 2012 reached end of support on January 10, 2017, and is no longer officially available for download. Its Windows Essentials support page also warns about unofficial Windows Movie Maker downloads. If you do not have trusted original media, replacing one DLL is not a reliable substitute for a complete installer.

Fix 4: Check Windows Security quarantine
Windows Defender or another antivirus program may have removed wldlog.dll.
- Open Windows Security from the Start menu.
- Select Virus & threat protection.
- Select Protection history.
- Review recent detections.
- Select the detection related to the Windows Live installation.
- Read the detection details before taking action.
Restore the file only if you have verified that it belongs to the legitimate Windows Live installation and the detection is a false positive. Do not restore a copy obtained from an unofficial DLL site. If the file was suspicious, remove it and run a full scan instead.
Microsoft explains the risks of restoring quarantined items in its guidance on Protection history. Defender may detect the file again after restoration.
Fix 5: Use DISM and SFC only for broader Windows corruption
wldlog.dll is not normally a protected Windows system DLL, so System File Checker is not expected to download or restore it. Use these commands when other Windows features are also malfunctioning, the error followed system corruption, or Windows reports additional damaged components.

- Restart Windows and test the affected application.
Microsoft recommends running DISM before SFC. These commands repair Windows components, not necessarily a third-party Windows Live DLL. If the commands report no integrity violations, return to repairing or reinstalling Windows Live.

Repeatedly running SFC and DISM without knowing what changed can make troubleshooting harder. Outbyte PC Repair can scan for broader Windows problems and show what it identifies, while its repair functions require the full version; reinstalling the Windows Live application remains the definitive fix for this app-specific file.
Fix 6: Restore the system after a recent change
If wldlog.dll worked until a recent update, driver installation, or software change, System Restore may return the related files and settings to an earlier state.
- Press
Win + R. - Enter
rstrui.exe. - Press Enter.
- Choose Next.
- Select a restore point dated before the error began.
- Select Scan for affected programs if available.
- Review the changes.
- Select Finish and allow Windows to restart.
Microsoft’s System Restore guidance explains that the process normally preserves personal files while rolling back system files, registry settings, and installed programs.

Fix 7: Update drivers only when evidence points there
A driver is not the usual cause of a missing Windows Live DLL. Check drivers only if the error began immediately after a hardware change, Windows update, or driver installation, or if Device Manager shows a related warning.
- Right-click Start and select Device Manager.
- Expand the category for the affected hardware.
- Right-click a device with a warning icon.
- Select Properties and review the General and Driver tabs.
- Use Roll Back Driver if the option is available and the problem began after an update.
- Otherwise select Update driver → Search automatically for drivers.
- Restart Windows and test the Windows Live application.
Do not disable random devices or install drivers from unverified download pages. Outbyte Driver Updater can scan for outdated drivers and identify which versions need attention, while driver installation through the full version is optional; it is not a replacement for repairing the Windows Live program itself.
Do Visual C++, DirectX, or .NET fix this error?
Usually, no. There is no evidence that wldlog.dll is a DirectX, Visual C++ redistributable, or .NET runtime file.
Install or repair one of those runtimes only when the exact error identifies a missing dependency from that runtime or another application also requires it. Installing unrelated runtime packages will not reliably restore a Windows Live shared DLL and can leave the original installation problem unresolved.

Why regsvr32 is usually the wrong fix
Do not routinely run:
regsvr32 wldlog.dll
regsvr32 is intended for DLLs that support COM self-registration through an exported DllRegisterServer function. A missing or misplaced Windows Live helper DLL is not repaired simply by registering it.
If regsvr32 reports that DllRegisterServer is missing, that normally means the DLL is not a self-registering COM server. It does not prove that another copy should be downloaded. Microsoft documents this behavior in its regsvr32 reference and DLL self-registration guidance.
Why random DLL downloads are unsafe
Downloading an individual wldlog.dll from an unknown source can provide:
- Malware or a tampered file
- The wrong Windows Live release
- The wrong architecture
- A file with missing dependencies
- A copy that does not match the application’s other shared files
It may also hide the real problem, such as a broken installer, antivirus quarantine, or a missing dependency. The safe sources are the repair function in the existing Windows Live installation and trusted original installation media. Microsoft does not currently provide a supported standalone wldlog.dll download.
If Windows Live Essentials is no longer installed
If the suite is absent from Programs and Features, first preserve any Windows Live Mail data. Then check whether you have trusted original installation media from the same Windows Live product family.
If the installer registration is damaged, use Microsoft’s official Program Install and Uninstall troubleshooter when it is available for your Windows version. Restart afterward, then repair or reinstall from verified media.
Do not treat an archived copy of an installer as a current Microsoft-supported download. Windows Live Essentials is retired, so moving to a supported mail, photo, or video application is safer than depending on a legacy suite indefinitely.
FAQ
Is wldlog.dll part of Windows 10 or Windows 11?
No. It belongs to legacy Windows Live software. Windows 10 or Windows 11 may display the error when an older Windows Live application is still installed, but Windows does not normally supply this DLL as an operating-system component.
Why is it in Windows LiveShared instead of the app folder?
Windows Live applications share common components. A damaged installation can leave the file in the shared directory while the application fails to locate it. Copying it to the application directory was reported as a workaround for some installations, but repairing the suite is preferable.
What does “not designed to run on Windows” mean?
It can indicate a corrupted file, an architecture mismatch, or a missing dependency. The wording alone does not establish which component is at fault. Reinstall the matching Windows Live component rather than selecting a DLL by version or file size.
Should I copy the file to System32?
No. Keep it with the Windows Live installation. Copying an application DLL into a Windows system directory can create further conflicts and does not repair the parent application.
What should I do if the repair leaves wldcore.dll and wldlog.dll present but the app still fails?
Check the application directory, antivirus history, and the exact error text. The loader may be unable to find another dependency. If the installation remains inconsistent, back up application data and reinstall the complete matching Windows Live component.

It may continue working on some systems, but Microsoft no longer supports or distributes it. Expect compatibility and security risks, and plan to migrate away from the legacy application when possible.
Final diagnostic checklist
Before seeking further help, record:
- The affected application
- Whether Windows is 32-bit or 64-bit
- The exact error wording
- The full path where
wldlog.dllwas found, if present - Whether Windows Live was recently installed, removed, or repaired
- Whether Windows Security quarantined the file
- Whether other Windows applications are also failing
Those details distinguish a missing Windows Live file from a missing dependency, a quarantined file, and broader Windows corruption.
