Customer profile

The main business of AOS DATA, Inc. is the development and sale of utility software for the Windows operating systems. In particular, for 17 years straight in Japan, AOS DATA has been providing the No. 1 client PC data recovery software, “FINAL DATA”, which has become the de facto standard for this application.

Problem statement

The various products from AOS DATA, Inc., including Final Data, are preinstalled on Windows PC OEM products. They urgently need to respond to OEM makers’ requests to develop a Windows Store version of the product. They are considering developing a universal Windows platform (UWP), but they anticipate that project would entail substantial man-hours and costs. A major challenge associated with system utility software is the need for system administration rights. There are multiple technical challenges during conversion:

  1. The current installer cannot be converted to a UWP App using the Desktop App Converter.
  2. FINALDATA being a system utility required administrative privileges to run the app.
  3. When using administrative privileges, desktop bridge security mechanism messages are displayed.

To handle these issues, we took the following steps:

Solution, steps, and delivery

  1. Held Hackfest (intensive technical implementation and coding session) for Desktop Bridge.
  2. Discussed issues on running UWP App of FINALDATA.
  3. Published UWP App to Windows Store.

1. Hackfest

In the Hackfest, the procedure was as follows:

  • Discuss with users on how do get administrative privileges.
  • Discuss with users on how to co-exist with desktop bridge security.
  • In case of issues, discussed and decided on the steps to resolving them.
  • As required, provide new sample code of script

    We offer the specific technique, and make concept codes. By concept codes, we understood “can exist together desktop bridge security”. So we provided new application structure as FINALDANAT launch procedure. Of course, this methodology includes security risk. So we don’t publicize this concept code.

As a result, they learned variety technique of administrative privileges and how to convert methodologies. They went ahead with Windows Store. A customer quote is as follow.

“We get to convert FINALDATA to a Windows Store app without adjusting the executable file.The app is now on Windows Store, and outcome is still yet to see since it was only a week ago. However, we already appreciate that FINALDATA is now on Windows Store, easily found from many users, and hoping it helps the app be widely used by many customers.” by Koji Kinoshita – Senior Developer
