• 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="*"/>
  <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.DirectOffice" version="4.1.0.0" publicKeyToken="8fb06cb64d019a17" processorArchitecture="msil"/>
    </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}
