 How can I solve "Class not registered." error message?

    Install Microsoft .NET Framework 4 or higher. Use .NET Framework Detect utility to check whether Microsoft .NET Framework 4 or higher is installed.
    Create manifest file yourapplicationname.exe.manifest (change yourapplicationname accordingly to the name of your application):

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
      <assemblyIdentity version="1.0.0.0" processorArchitecture="*" name="yourapplicationname" type="win32"/>>

      <dependency>
        <dependentAssembly>
          <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0"
            publicKeyToken="6595b64144ccf1df" language="*" processorArchitecture="*"/>
        </dependentAssembly>
      </dependency>

      <dependency>
        <dependentAssembly>
          <assemblyIdentity name="Winsoft.ZXing" version="0.14.1.0" publicKeyToken="c2371442b2cedf55" processorArchitecture="x86"/>
        </dependentAssembly>
      </dependency>
    </assembly>

    Embed yourapplicationname.exe.manifest file to your application: Select Delphi menu Project/Options.../Application. Change Manifest File combobox to Custom and select yourapplicationname.exe.manifest file in Custom manifest edit box.
    Instead of embedding yourapplicationname.exe.manifest file to your application, you can comment "{$R *.res}" line in yourapplicationname.dpr file and use external yourapplicationname.exe.manifest file:

    // {$R *.res}
