Notes on installer exe format

We are now using a new digital signature, so you may receive a warning when downloading or installing.
This warning occurs because the digital signature is not yet recognized by some systems, but there is no problem with the software itself.
You can download it safely.

If you see a warning, you can still proceed with the download by following the steps below:

For Microsoft Edge

Click "・・・" and click "Keep".
Then click "Show more" and "Keep anyway" to begin the download.
(The operation method may differ depending on the version of Microsoft Edge.)

For Google Chrome

When you see "Suspicious download blocked", click ">".
Next, click "Download suspicious file" to begin the download.
(The operation method may differ depending on the version of Google Chrome.)

If you do not have administrator privileges, a message such as "Setup cannot be executed" appears and installation cannot be performed.
In that case, ask the system administrator to install it.
Windows may need to be restarted. If you are prompted to restart, please restart Windows before using TFV.

If a screen like the one shown below appears, click "More info" and click the "Run anyway" button.
