Ok, figured it out, needed to create the two registry entries...

The license is stored in the registry, under the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Licensing\QuickOPC\Multipurpose

In order to install the license, this key and anything that is beneath it, must be properly deployed to the target machine.

Note: On 64-bit systems, the license is stored in 32-bit registry. When the registry is accessed from 64-bit application, you must use the following key instead:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Licensing\QuickOPC\Multipurpose

Hello.

If you do not use the installation program (there is also a Production Installer just for this purpose), you need to create empty registry key(s) that holds the available component name.

HKEY_LOCAL_MACHINE\SOFTWARE\Licensing\QuickOPC
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Licensing\QuickOPC

You can, however, also embed the license key right into your project, and no licensing steps will then be necessary at the target computer:

I hope this helps.

Best regards

Client cannot install license - cannot select component was created by ScottEwine
I have created a visual studio .net console app for a customer, and they are having trouble licensing it. They cannot select a component to license. What do they need to do for this to be selectable? I have purchased "QuickOPC Ultimate, Single Developer + Runtime Free License, With 5 Years Upgrade Assurance".

What do I need to provide to the customer, I think just the licensemanager.exe and the key .bin file, is that correct?

Any help would be appreciated.

Scott
