Download

The download is free to grab — it needs the license key from your purchase to unlock.

Download Daito's Opti (.zip)

Your license key arrives by e-mail with your order. Without a key the app only shows the activation screen (and its license-free "restore changes" view).

Installing

• Unzip anywhere (e.g. your Desktop) — there is no installer to run.
• Double-click DaitosOpti.exe.
• Windows asks for administrator permission (the tweaks need it) — click Yes.
• Windows SmartScreen may warn about an unknown publisher — click "More info" → "Run anyway". That prompt is normal for a new unsigned download and not a verdict on the tool; the app is a packaged PowerShell script whose full source stays embedded and inspectable.
• Paste your license key when the activation screen appears. Done.

Lost your key?

• Search your inbox for "Daito's Opti" — the key is in your order confirmation.
• Still stuck? Mail daitoak@outlook.com from the address you bought with, and we'll sort it out.
