I tried the tip from Yukito. the message in japanase of missing register did stop, but now there's a new japanese message saying "Application initialization error". tried the tip 3 times, then the 4 time i got "! Cannot execute "C:\Users\(info) Revision II\io_r2_en.exe". for the 5 try i closed and openned the archive again, and got the error message again, how is this solved?

I am probably writing this to you too late as you have probably already found this out, but, if you are having a problem running the game getting a message in japanese like "missing register" you have to run the file "ioregadd.bat" after which when you click the "io_r2_en.exe" again to run the game it will now launch. If this wasn't your problem please forgive my unsolicited advice.
