Key changes: 64-bit Development


  • The components now allow development for x64 platform running in 64-bit mode (it was previously possible to run the programs developed with QuickOPC.NET on 64-bit systems, but only in 32-bit processes). Separate set of assemblies is provided for x64 development, however the interfaces remain identical. Development for x86 platform (32-bit) continues to be fully supported.
  • For use on x64 platform, supporting software such as License Manager was also ported to 64-bits.


  • The setup program now allows the user to select which platform support (x86, x64, or both) will be installed for development.
  • On x64 platform, corresponding versions of Microsoft Visual C++ Redistributables, Demo application, License Manager, OPC Simulation Server, and other programs will be automatically chosen and installed.
  • On x64 platform, corresponding version of OPC Core Components 3.00 Redistributables will be automatically chosen and installed (this includes proper OPC proxies and stubs).
