license [using NuGet]

Replied by support on topic license [using NuGet]
NuGet is primarily a tool to resolve build-time assembly dependencies. QuickOPC contains much more than just the assemblies. We provide NuGet packages for QuickOPC in order to make the development and building easier, but you are still encouraged to install the whole product. There are parts that, by their nature, should not or cannot be inside the NuGet packages - and the License Manager tool is one of them.

In order to install the license in your case:
  1. Download the product from our Web site ( ).
  2. Install it. All "express" installation choices (on the 2nd page of the installation wizard) include the License Manager tool.
  3. After the product is installed, from the Launcher tool, start the License Manager.
  4. Make sure "QuickOPC" is selected in the "Component" drop-down, and press the "Install license" button. Browse to the supplied license file and press "Open".

Related documentation:
For information, I am also attaching a "readme.txt" file from the NuGet packages that explains the differences between them and the full product.

I purchased OPCClient standard product. I use OPCLabs dlls using Nuget. How do I install the product using the licensekey. It says I should install using license utility manager. Should I download license utility manager from OPClabs website? Please send the instructions on how to use the product using the license.
