From the update of yesterday 's Minecraft Launcher, when Language was specified as Japanese, Minecraft Launcher did not start up. After repeating reinstallation, I confirmed that the cause will occur if Language is specified as Japanese. It does not occur if you are in English. Please fix it.

I'm sorry, I will correct this. It was useless if I changed the symbolic link(cf: C:→D: ). It seemed that I was able to start up while I was repeating the reinstall, forgetting to erase ".minecraft" of roaming. Language was irrelevant, it was a matter of specifying a symbolic link. I apologize to you for a fuss over.
