Comment on Shimeji FAQ by Charm-Box
Yes! It's a few more steps, but it works! You have to download Winrar, and download the rar version of the shimeji. And open it in winrar. It should work that way ^-^
Do you know if you can do this with a Japanese installed shimeji?? I downloaded a shimeji off of Pixiv and I got the same problem where it asked me to update my Java to Java 6, even though I had already updated my Java when it asked. You said that it works if we open the shimeji in WinRar.... but can I do that with a Japanese shimeji? O.O Also, did you happen to be using a Windows XP because I dunno if running a shimeji on an XP is a problem as well...?? 
it works with Japanese shimeji, but I'm not sure about xp xD you can try.
Alright, I'll try it anyways... thanks though!
