u downloaded a wrong version of Java software(seen the installation requirements on download web of smartpls), the correct version of Java is J2SE JRE(jre-1_5_0_22-windows-i586-p). u can easily findout the right version at Java.sun.com. Also, GD+ version is named as "WindowsXP-KB975337-x86-ENU",which can be downloaded at http://www.microsoft.com/downloa ... ng=en&id=18909.
