Notes on installer exe format

Due to the adoption of a new digital signature, you may see warning messages during download or installation.
These warnings appear because the new signature has not yet been recognized by some systems, but there are no issues with the software itself.
It is safe to download the software.

Even if a warning appears, you can continue the download by following the steps below:

For Microsoft Edge

Click on “...”.

Click “Keep”.

Click “Show more”.

Click “Keep anyway” to complete the download.

Currently, due to a Windows issue, the publisher name appears garbled because it is in Japanese, but it shows as “ナリー・ソフトウエア(Nary Software)”.
(Note: Steps may vary depending on the version of Microsoft Edge.)

For Google Chrome

If you see “Blocked suspicious download”, click “>”.
Then click “Download suspicious file” to begin the download.
(Note: Steps may vary depending on the version of Google Chrome.)

Installation Notes

Administrator privileges are required to install the software.
If you do not have admin rights, a prompt to enter an administrator password or a message such as “Setup cannot be run” will appear, and the installation will not proceed.
In that case, please ask your system administrator to perform the installation.
