這個需要安裝序列號的好象是正式版？裝好之後沒有VBOX。

安裝程式似是用InstallAnywhere for Java製作的。有個編譯後的安裝指令碼檔案InstallScript.data，但實際上是個*.class檔案，裡面有判斷註冊碼的東西。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);
再把臨時目錄下的IAclasses.zip解開，找到SetSerialNumber.class、SerialNumberManager.class、SerialNumberInstallPanel.class，真正的註冊碼判斷就在這裡面。有興趣的自己分析吧。真正的程式檔案都在installer.zip中的raw目錄下。
