Distribution Formats

Connectivity Software products come in multiple distribution formats. Not every distribution format is available on all operating systems or for all Connectivity Software products. Following distribution formats exist:

• Setup Program. This is what you get when you directly download the software from the Web site (https://www.opclabs.com/download), or obtain it on a distribution media such as CD or flash disk. The Setup program is only available for Windows. Use the Setup program if you are targeting .NET Framework, .NET 8+, Python, COM, or Excel development platform. Also, use the Setup program if you want to use the Excel Connector.
• NuGet Packages (NuGet is a package manager for development tools such as Visual Studio). The packages are hosted on www.nuget.org, and you need to use a NuGet client in order to access them. You will use the NuGet packages when you developing with QuickOPC or OPC Wizard, and are targeting the .NET Framework or .NET 8+ as a development platform. In the absence of a setup program, QuickOPC and OPC Wizard provide several smaller downloads that complement the NuGet packages - such as archive files with examples, etc.
• Python Packages . The packages are hosted on https://pypi.org/, and you will typically use the 'pip' tool in order to access them. You will use the QuickOPC Python packages when you are using QuickOPC in Python. In the absence of a setup program, QuickOPC provides several smaller downloads that complement the Python packages - such as archive files with examples, etc.
