aeinv.dll File Guide & Troubleshooting

File Description

aeinv.dll is a legitimate Microsoft system component known as the Application Experience Inventory library.

• It gathers telemetry data about application compatibility and usage for the Windows Customer Experience Improvement Program.
• It helps Windows determine if older programs will run correctly on newer versions of the OS.

Standard File Location

The authentic file is strictly located in the Windows system directory:

• C:\Windows\System32\aeinv.dll (on 64-bit systems for 64-bit processes, or 32-bit systems)
• C:\Windows\SysWOW64\aeinv.dll (on 64-bit systems for 32-bit compatibility processes)

Note: If you find this file located in temporary folders, user profiles, or the AppData directory, it is likely malware disguised as a system file.

How to Fix aeinv.dll Errors Without Downloading

Do not download this file from third-party "DLL downloader" websites. These files are often outdated, bundled with malware, or cryptographically unsigned. Instead, use these built-in Windows tools to repair or replace it safely.

1. Run the Deployment Image Servicing and Management (DISM) Tool

DISM checks Microsoft servers to replace corrupted system image files.

1. Right-click the Start button and select Terminal (Admin) or Command Prompt (Admin).
2. Type the following command and press Enter:

   DISM.exe /Online /Cleanup-image /Restorehealth

3. Wait for the process to reach 100% completion (requires an internet connection).

2. Run the System File Checker (SFC)

SFC scans your local system files and replaces missing or damaged copies using the healthy cache generated by DISM.

1. In the same Administrator Command Prompt window, type:

   sfc /scannow

2. Press Enter.
3. Restart your computer after the verification phase finishes.

3. Disable the Compatibility Appraiser Task

If the error occurs as a recurring popup or causes high CPU usage, you can temporarily disable the scheduled task that utilizes this DLL.

1. Press Win + R, type taskschd.msc, and press Enter to open Task Scheduler.
2. Navigate to: Task Scheduler Library > Microsoft > Windows > Application Experience.
3. Right-click Microsoft Compatibility Appraiser in the middle pane.
4. Click Disable.

4. Register the DLL Manually

If the file exists but Windows fails to recognize it, re-registering it in the registry environment can resolve the issue.

1. Open Command Prompt as an Administrator.
2. Type the following command and press Enter:

   regsvr32 %windir%\system32\aeinv.dll

3. Click OK on the confirmation popup.
