Advanced Manual Solutions
If you’d rather handle it yourself, here are some reliable methods. Each method comes with pros and cons so you can choose what works best for you.
1. Run System File Checker (SFC)
Windows has a built-in SFC tool that scans for missing or corrupted system files, including DLLs, and automatically repairs them using cached files.
Steps:
Press Windows + S, type cmd, and right-click Command Prompt > Run as administrator.
Type: sfc /scannow and hit Enter.
Wait until the scan completes.
Restart your computer and check if the issue is fixed.
2. Use DISM to Repair Windows Image
If SFC can’t fix the issue, DISM digs deeper. It restores the system image and ensures that corrupted DLL files like optanedt_x64.dll are properly replaced.
Steps:
Open Command Prompt as administrator.
Type: DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Let the process finish.
Run sfc /scannow again for good measure.
3. Update Intel Drivers Manually
Since optanedt_x64.dll is tied to Intel’s Optane memory, updating Intel drivers may restore the DLL and resolve related crashes or missing file errors.
Steps:
Visit Intel’s official support page.
Download the latest Intel Optane drivers.
Install them and restart your PC.
Warning: Always download drivers directly from Intel to avoid malware risks.
4. Reinstall the Affected Program
If the error only happens when launching a specific app or game, reinstalling it may restore the required DLL without touching system-wide files.
Steps:
Press Windows + R, type appwiz.cpl, and hit Enter.
Find the problematic program, right-click, and choose Uninstall.
Restart your PC.
Reinstall the program from its official source.
What to Do If Nothing Works
Run Windows Update to install the latest patches.
Roll back recent driver updates if the error started after an update.
As a last resort, perform a System Restore to a date before the issue appeared.
If even that fails, you might be dealing with deeper system corruption, and a Windows reset/reinstall could be necessary.
