When I try to open the app, it says "Windows protected your PC".

When you try to launch the app for the first time, you may see a screen like the one below.

In this case, click "Details" and then click "Run".

Why am I getting such warnings?
Depending on the Windows specifications, a warning may be displayed to call attention when using the app for the first time.
Since IZANAMI is a tool for creating sales lists, such warnings may be displayed.
