Secure the installation of a software by prompting for a serial number

Question

I am working on a project (Java project) and using Inno Setup 5 to create an installer. How can I secure the use of the install.exe and ask a serial number during the installation?

Thanks for the help.

Answer 1

Inno Setup has a built-in functionality prompting for a serial number on the optional "User Information" page and verifying the entered number.

• set the UserInfoPage directive to yes;
• implement the CheckSerial event function to make the Inno Setup prompt the user for the serial number and to verify it;
• use the {userinfoserial} constant in the [Registry] section to save the entered and verified number to registry.

[Setup]
UserInfoPage=yes

[Registry]
Root: HKLM; Subkey: "Software\My Company"; ValueType: string; ValueName: "SerialNumber"; \
    ValueData: "{userinfoserial}"

[Code]

function CheckSerial(Serial: String): Boolean;
begin
  Result := (Serial = '123');
end;

For a more advanced implementation, see CustomPage for Serial Number in Inno Setup.

Answer 2

I works. I recommand to add in the InnoSetup script :

Flags: uninsdeletekey

When the program is uninstalled, delete the entire key.

[Registry]
Root: HKLM; Subkey: "Software\MySoft"; ValueType: string; ValueName: "AppInfo";  ValueData: "value" ; Flags: uninsdeletekey

I used this link to recover the key in my soft.

value = WinRegistry.readString (
                WinRegistry.HKEY_LOCAL_MACHINE,                             
               "SOFTWARE\\MySoft",          
               "AppInfo");
