Thank you.

The "Support Link" was in the email from the Web Shop.

Your example worked great.

all the best,

Hello.
Thank you for your interest in our products.

I would be interested in knowing where is the "support link" that does not work - we want to fix it. Was it in the email from the Web shop? Or elsewhere?

I suppose your question is about licensing the developed application on target machines. This can be done in multiple ways - such as using the License Manager and installing the license there, or by embedding the license into your application ( so that no additional steps are needed on the target computer). For start, go here:

-  www.doc-that.com/files/onlinedocs/OPCLabs-ConnectivityStudio...html#Licensing%20Elements.html

or right here:

-  www.doc-that.com/files/onlinedocs/OPCLabs-ConnectivityStudio...esource%20License%20Store.html

I would be happy to answer any additional questions you may have.

Best regards,

i have just purchased QuickOPC and am trying to make the license operational in my C# .netFramework 8 EasyUAClient application.  The support link provided with the license did not work so i dug around on the web site  and found way more information than i could use.  would you please send me an example of activating the license in my simple application.

thank you.
