Due to several questions in the posts:
I just confirmed the procedure to install AUmusicPort on an English Version Windows XP.
First, install Japanese font support from your windows CD.
The easiest way to do this is to:
1: go to start, control panel, Regional and Language options.
2: from there, choosing to enable Japanese will automaticly start the install process..
3: be ubergeek and do it any number of other ways you are more familiar with ;)
From Regional and Language options,
1: assure nothing got jacked on the install.. so, check Languages tab, click on details, and make sure your input system is still US (or whatever your keyboard is)
2: Cancel out and go to Advanced.
3: here is where the fun is. Langage for Non-Unicode Programs... Set it to Japanese, and you will need to reboot.
Now, here is the rub (and thus the toggling bit..) you COULD leave it set to Japanese. This will have the effect of always making AU look right. The problem now is that EVERY PROGRAM YOU INSTALL WILL DEFAULT TO JAPANESE... yeah.. every thing you do after setting this will default.. even if English is an available option in a Unicoded application.
The problem with AuMP is that it is poorly Unicoded.. So, if you change the setting back to English, its jibberish again.. but if you leave it in Japanese, all your other programs (and most especially new installations) will be turning Japanese..
So, to avoid leaking Japanese onto every other program you use or install.. you need to set the setting BACK to English.
Thus, you need to toggle this when you are using Amp, and deal with a reboot.. SOMETIMES.. one you get to know where things are, you might be able to live with the partial jibberish..
