I have a business application which runs on client machine with XP. When I execute the application, it will first authenticates the user by collecting the system ID which has to be registered using the serial key given by the owner. Once the
registration takes place, only then the application has to open. Recently, I had to re-install XP Pro (SP3) on my PC. Now, the same application, when executed on my PC with XP or Laptop with Windows 8 with XP compatibility, it does not pop the authentication
window, instead, directly opens the application.
Without authentication, the app should not open. What is the solution.
PN:
1. I cleaned up the existing XP from my desktop and reinstalled XP on D: drive instead of C: drive.
2. The application requires .NET framework 3.5 which is also installed, but installation of SP3 has also installed another version
of .NET framework.
