推荐答案

对于磁盘空间检查，将运行脚本"操作添加到安装程序的启动"节点，并将其脚本设置为

For the disk space check, add a "Run script" action to the "Startup" node of your installer and set its script to

if (SystemInfo.getFreeDiskSpace(context.getInstallationDirectory()) < 2000000000) {
    Util.showErrorMessage("You need at least 2 GB of free memory");
    return false;
}
return true;

然后，将操作的失败策略"属性设置为失败时退出":

Then, set the "Failure strategy" property of the action to "Quit on failure":

对于Java版本检查，请转到常规设置"->"Java版本"，然后将最低版本设置为1.6:

For the Java version check, go to General settings->Java version and set the minimum version to 1.6:

如果安装程序找不到最低版本的1.6 JRE，它将显示一个对话框，并显示相应的消息.

If the installer cannot find a 1.6 JRE with that minimum version, it will display a dialog with an appropriate message.
