It’s probably due to language. If Japanese is not up properly (especially in this case, because typing is part of it) it will probably refuse to install.
The Japanese text displays fine in the software I was using, either Windows XP or one of my disc burning programs. A 1152 error seems to be a temp folder problem. I'll have to look into it. The video looked interesting if nothing else. The program itself doesn't display the Japanese language on the buttons you have to press but the info files display perfectly. I could probably save them or else print them out. The order of which buttons to press is actually made easy by the program itself, as it highlights those. Since this is made for a very young player, I could see them doing that. I tried burning the file to a CD and then running that or else using a Virtual Drive and running it that way and ran into the 1152 error both ways. I'll have to try it again tonight after work...
