Install MEGA

Five steps.

MEGA Setup checks your PC before it copies anything.

  1. Download

    Download MEGA.exe, then verify it (see below).

  2. Run it

    A small splash unpacks the installer, then Setup walks you through it.

  3. System check

    Setup checks Windows version, disk space, pending restarts and internet.

  4. Pick options

    Choose a profile, a folder or drive, shortcuts and a restore point first. Nothing is applied until you press Apply in MEGA.

  5. Activate

    Enter your key (or do it later), review what Setup will do, then install.

If anything fails, Setup puts the previous version back automatically and verifies every file. For the Optimizer: run as administrator, approve the UAC prompt, pick what you want, keep Create a restore point on, and run.

Verify before you run

Check the SHA-256 checksum.

New releases can trigger a Windows SmartScreen warning until they build download reputation. A warning is not proof either way, so do not just click past it: verify the file.

  1. Run the command on the right in PowerShell after downloading.
  2. Compare the result with the hash for that release in the Trust center.
  3. Optionally look the file up on VirusTotal; the Trust center links each one.
  4. If the hash matches and the scan is clean, it is the file we published.
Get-FileHash "$env:USERPROFILE\Downloads\MEGA.exe" -Algorithm SHA256
If Defender names a specific threat, do not run the file. Tell us on Discord and we will investigate. See also What to do if SmartScreen or Defender warns you.

Windows

Windows 10 version 1809 or newer, or Windows 11. 64-bit.

Admin rights and internet

MEGA does not need admin rights to install or run; items marked Admin ask Windows when you use them. It needs the internet once to activate, then for update checks and tests you start.
