Thank you for viewing! Although it's not the latest version, I purchased this from Media 5 for self-improvement. I plan to list more items as well. It seems there's a downloadable version available now. This product is the CD-ROM version. It includes a CD-ROM for learning materials and a CD-ROM for voice synthesis. You can study with the textbook, vocabulary list, and practice questions on your computer. Please check the photos for details. Installation has been confirmed on Windows 10 and 11. The original price was 13,440 yen. I'm offering it at a lower price. There are ID numbers and other information written on the top of the inner box, but they are no longer in use, so please don't worry. I've discounted the price accordingly. Thank you for your consideration.
