Update: July 22, 2025

Hello everyone,

We want to sincerely apologize for the recent issue with our installer.

Unfortunately, a bug slipped through our testing process that affected installation for both the current user and all users. We’re truly sorry for the inconvenience this may have caused.

Thanks to your quick feedback, we were able to identify the problem early. We really appreciate your support and responsiveness – it made a big difference.

As a result, we’ve decided to temporarily remove the new installer and revert to the previous version to ensure stability. We’re currently working on a new developer release and plan to roll it out later this week.

Thank you for your patience and understanding.
