Evaluation License

Nevron Open Vision is distributed with a 60 day free, non binding evaluation / trial license. You are free to test the fully functional product for 60 days, after which you must either license the product or remove it from your system.

The evaluation license is automatically activated when you install the product on a designer or server machine. However, when trial mode expires, the message "The evaluation period has expired" will appear in place of the controls.

Note: The evaluation version is fully functional

Product Activation

Nevron Open Vision activation is achieved by entering one or more license keys to the machines running the software.

The product is distributed as unified binaries (DLL) for both evaluation/trial and production uses. No additional installations / uninstallations need to be performed.

In order to activate the product you need to acquire a number of developer/server/desktop license keys. Some of these keys are bound to the machine(s) using the controls. When you contact Nevron Software to license the product you need to provide the machine id and the machine usage for each machine where you have the controls installed.

For example if you have one developer machine and one production server you need to provide two machine ids. The machine id can be obtained from the "License Key Manager" application or by running some of the examples shipped with the controls (when in Evaluaton mode all controls show the current machine id as part of the evaluation message).

Windows (WinForms and WPF)

When you obtain the license key(s) from Nevron you need to enter them in the License Key Manager application shipped with the suite. It can be started from Start\All Programs\Nevron .NET Vision[Version Number]\License Key Manager program shortcut:

Press the "Add..." button and enter the license key. Then press Ok and repeat for all provided keys. After you enter all license keys you need to press "Save" in order to store the license. 

You can enter all license keys on all machines running the controls. The controls will automatically determine which license keys are valid for a particular machine.

Silverlight and Mac

For Silverlight and Mac applications you need to enter the license key(s) you obtain from Nevron inside the main entry point of the application. For details check the following topics:

It is recommended to contact a sales representative prior to purchasing.

Desktop Redistribution

Nevron controls are royalty free for redistribution in compiled desktop applications. Each developer license also includes a perpetual desktop redistribution license. In order to distribute such applications you must embed a desktop license key in the application by using the following code:

Example Title
Copy Code
using Nevron.Nov;
...
NLicense license = new NLicense("licenseKey");
NLicenseManager.Instance.SetLicense(license);
It is important to apply the license before any constructors are called. The LockLicense property instructs the manager that no further license changes must occur.
