You cannot download a replacement memtest.exe because it is a protected core component of Windows, but you can fix it by repairing your system image or choosing a third-party alternative.

The built-in Windows Memory Diagnostic tool (memtest.exe) usually fails or errors out due to corrupted system files or faulty RAM hardware.

Here is how to fix it without downloading anything.

1. Run the SFC and DISM Tools

Windows has built-in repair tools that automatically find and replace corrupted system files, including memtest.exe.

Press the Windows Key.
Type cmd.
Right-click Command Prompt and select Run as administrator.
Type DISM.exe /Online /Cleanup-image /Restorehealth and press Enter.
Wait for it to finish, then type sfc /scannow and press Enter.
Restart your computer.

2. Re-register the Windows Boot Manager

If the boot configuration data (BCD) cannot find the path to memtest.exe, it throws an error. You can rebuild this path via Command Prompt.

Open Command Prompt as an administrator.
Type bcdedit /bootsequence {memdiag} /addfirst and press Enter.
This forces Windows to prioritize and correctly map the memory diagnostic tool on the next boot.

3. Check for Pending Windows Updates

A buggy Windows update can break system utilities. Installing pending patches often replaces the broken executable.

Open Settings (Press Windows Key + I).
Go to Update & Security (or Windows Update).
Click Check for updates.
Install all available updates and restart.

4. Reseat Your RAM Hardware

Sometimes memtest.exe crashes because your physical RAM sticks are loose or dusty, causing the software to fail instantly.

Turn off your PC and unplug the power cable.
Open the computer case.
Remove the RAM sticks from their slots.
Clean the slots with compressed air.
Firmly click the RAM back into place.

Alternative (If it still fails)

If you absolute need to test your RAM and the built-in tool is permanently broken, you will have to use an external tool like MemTest86. While this requires a download, it runs from a USB drive and is much more accurate than the built-in Windows tool.
