The Windows warning on first start

The first time you start DreamHelper, SekaiHelper and CanisHelper, Windows shows "Windows protected your PC". These apps carry no digital signature naming their publisher, and Windows shows this warning when it starts an unsigned app it does not recognise yet. It does not mean a virus was found.

When you see "Windows protected your PC"

The "Windows protected your PC" screen (Japanese Windows), with "More info" and "Don't run"
The screen after "More info": App: dreamhelper.exe, Publisher: Unknown publisher, with "Run anyway" and "Don't run"
  1. Click "More info"
  2. Check that "App:" is one of dreamhelper.exe, sekaihelper.exe, canishelper.exe. "Publisher:" reads "Unknown publisher"
  3. Click "Run anyway"

Once you click "Run anyway", the same app does not show it again, nor after you update it from inside the app. It can show again when you download and extract a new zip from the account page.

Remove the warning before extracting

Do this before you extract the zip and the app starts without the warning. Do it only for a zip you downloaded from the account page.

The General tab of the zip's Properties, with the "Unblock" checkbox next to Security at the bottom
  1. Right-click the downloaded zip and open "Properties"
  2. On the "General" tab, tick "Unblock" next to "Security" and click "OK"
  3. Right-click the zip and extract it with "Extract All"

When you see "Open File - Security Warning"

The "Open File - Security Warning" screen: the publisher could not be verified, with "Run" and "Cancel"

When the app is started from somewhere other than File Explorer, Windows may ask "The publisher could not be verified. Are you sure you want to run this software?". Check that "Name" is the product's exe and click "Run".

If the app does not start

Do not turn off Microsoft Defender or SmartScreen. Let the warning through only for the product apps you downloaded from the account page.
