这个需要安装序列号的好象是正式版？装好之后没有VBOX。

安装程序似是用InstallAnywhere for Java制作的。有个编译后的安装脚本文件InstallScript.data，但实际上是个*.class文件，里面有判断注册码的东西。如下：

        show_Serial_Number_Panel_Enter_Serial_Number = new SetSerialNumber();
        show_Serial_Number_Panel_Enter_Serial_Number.setPrefix(true);
        show_Serial_Number_Panel_Enter_Serial_Number.setMutuallyExclusiveProducts(true);
        show_Serial_Number_Panel_Enter_Serial_Number.setSeedStr("*#&*,&*,!*#!},!*,!}#!*,&*#&");
        show_Serial_Number_Panel_Enter_Serial_Number.setNoOfSerialNumbers(1000L);
        show_Serial_Number_Panel_Enter_Serial_Number.setMatchingProduct("Product");
        show_Serial_Number_Panel_Enter_Serial_Number.setInstallPanelClassName("com.zerog.ia.installer.installpanels.SerialNumberInstallPanel");
        show_Serial_Number_Panel_Enter_Serial_Number.setAllowBlankInput(false);
        show_Serial_Number_Panel_Enter_Serial_Number.setSerialNumberEntered("UserEnteredSerialNumber");
        show_Serial_Number_Panel_Enter_Serial_Number.setPrompt("Please Enter the Serial Number: ");
        show_Serial_Number_Panel_Enter_Serial_Number.setStepTitle("Enter Serial Number");
        show_Serial_Number_Panel_Enter_Serial_Number.setNoOfProductsStr("(|%({e$@+.");
        show_Serial_Number_Panel_Enter_Serial_Number.setStaticStringStr("+`^+:+|(}:+!(})");
        show_Serial_Number_Panel_Enter_Serial_Number.setSuffix(false);
        show_Serial_Number_Panel_Enter_Serial_Number.setAdditionalText("This Installer Requires a Serial Number to Continue");
        show_Serial_Number_Panel_Enter_Serial_Number.setNoOfDigitsStr("(!^(@@*e1.");
        show_Serial_Number_Panel_Enter_Serial_Number.setFileName("jvision142w_SerialNumbers.txt");
        show_Serial_Number_Panel_Enter_Serial_Number.setExternalID("SetSerialNumber.15");
        ProgressMonitor.updateScriptIncrement();
        jVISIO2_preInstallActions.addElement(show_Serial_Number_Panel_Enter_Serial_Number);

再把临时目录下的IAclasses.zip解开，找到SetSerialNumber.class、SerialNumberManager.class、SerialNumberInstallPanel.class，真正的注册码判断就在这里面。有兴趣的自己分析吧。真正的程序文件都在installer.zip中的raw目录下。
