How to create an installation package without a serial number from MSI

The tool used in this article: orca, can be downloaded in the http://www.crsky.com/soft/8680.html like orz
The following is an introduction to Orca:

Orca is a database table editor provided by Microsoft for Windows installer. Allows you to edit Windows Installer database files (. MSI), merge module files (. MSM), patch files (. MSP), and perform internal consistency calculation.Program(. CUB) file and patch creation attribute (. PCP) file. It is the best auxiliary tool for modifying and localized Windows Installer databases.
Main features include:
-You can add, delete, import, export, and recreate data tables at will;
-You can copy, paste, add, delete, and edit rows and cells at will;
-You can view data-type cells in decimal or hexadecimal notation;
-You can create and convert an application (. MST) file;
-You can verify the database, merge the modules, and view the dialog box;
-View and modify the abstract information;

Let's take the installation package of Kingsoft powerfoot 2005 as an example:
1. Use orca.exe to open the Powerword 2005.msi disk (do not press it on the disc and cannot save it)
2. Click "control" in the list on the left. (The control table stores the information about the controls used during installation)
3. Under the "control" column in the list on the right (the control here represents the definition name of the space), locate the "serialnumber" item.
4. In the corresponding row of this item, modify the content in the "text" column. The original content is <???? -???? -???? -???>, Put ???? Change the serial number.
5. Save and exit!

When you run Powerword 2005.msi again, you will find that there is a serial number at the step of entering the serial number, instead of entering it again!

After self-testing, some installation packages can be modified using this method, while others, such as the acrobat professional installation package, are still not entered during installation. The restriction should be imposed in the program, and this method cannot be modified. Can you modify other locations to achieve your goal? Please experiment with experts !~~
