Hello ! Same happened with me and follow the instruction . It all worked . Thank you. It might help : My system is Windows 8 and installed the 64 bit version of SH4 . On my computer was not slow, but I prefer to use the installer because it opened the window mentioned in the post and the icon was white. My attention to 32bit it says next to my Java version is 7. I hope I helped .I use a translator.
