How to Fix applistbackuplauncher.dll Errors Without Downloading

DLL errors are usually caused by file corruption, registry glitches, or interrupted Windows updates. You can fix this file safely using built-in Windows tools without downloading anything from risky third-party websites.

1. Run the System File Checker (SFC)

This built-in tool scans your system for corrupted or missing Windows files and replaces them automatically from a local cached backup.

Press the Windows Key.
Type cmd.
Right-click Command Prompt.
Select Run as administrator.
Type sfc /scannow and press Enter.
Wait for the scan to hit 100%.
Restart your computer.

2. Run the DISM Tool

If the SFC tool cannot find the clean backup file locally, the Deployment Image Servicing and Management (DISM) tool will repair the system image using Windows Update components.

Open Command Prompt as administrator (same as step 1).
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Let the process finish completely.
Run the sfc /scannow command one more time right after.
Restart your system.

3. Re-register the DLL File

If the file exists but Windows cannot read it properly, re-registering it in the system registry can resolve the issue.

Open Command Prompt as administrator.
Type regsvr32 applistbackuplauncher.dll and press Enter.
If you get an error path message, type the full path: regsvr32 C:\Windows\System32\applistbackuplauncher.dll and press Enter.
Click OK on the confirmation popup.

4. Install Pending Windows Updates

Since this file belongs to the core Windows app management system, a system update can overwrite corrupted versions with the newest stable release.
