Well i think that running this on Vista will turn the EMULATOR ON in order to run your application properly.
example: if you have a Win98 Application and you want to run it in WinXP then you can use this EMULATING PROCEDURE , but keeping in mind that it will NEVER WORK in the performance that you are expecting. ( like heavy Application i.e. Corel) or whatever.
so if you have a good high end hardware and you spent alot of $$$ on your PC then its USELESS here.
