It is free choice. On some people's systems the international installer is much easier to install than the so-called english installer. They use different types of installers. But I wonder
ukbobboy01, if you keep your installshield engines up-to-date (which is something many people haven't done which leads to their installation problems & resort to using the inter'l installer) perhaps you would be fine to use the english installer. I have a link in the sticky thread about installshield errors (in the installation/windows section) for updating these engines. But then I've found some people have had to go backwards from Java 1.5 to 1.4.2 due to problems on their setup.
PC's are so, so variable. Why doesn't evreybody go out & buy a mac & their problems would be solved. Hey no SP2 or installshield to contend with, etc. No ram limitations. No Viruses to be bothered with. lol
