Additional developer licenses cost less than your initial license, please contact us for a quote.

Site License

COMMON LICENSING QUESTIONS

 

  • Can I transfer my license?
  • Can I upgrade between editions?
  • How do I deploy my compiled applications?
  • How is the developer license delivered?
  • Do I have to pay annual fees to keep using my license?
  • Do you offer hardware key/dongle licenses?

Can I transfer my license?

You may transfer licenses between computers used by the licensed developer, or to a new developer within your company, provided you are on an active support and maintenance agreement.

You may not have more than one developer per license owned using the product at the same time.  Additional developer licenses are available at discounted prices, as are site licenses. Contact us for details.

We reserve the right to limit transfers if circumstances suggest there is an attempt to circumvent the per developer seat licensing.

Can I upgrade between editions?

You can upgrade between editions of the OPC Data Client - such as from Professional to Enterprise, for as little cost as paying the price difference, provided that you are on an active support and maintenance agreement. 

If you are not on an active support and maintenance agreement, you can still upgrade, but the cost to upgrade will include reinstatement of your support agreement. 

Please contact us for a quote if you are interested in an edition upgrade.

How do I deploy my compiled applications?

OPC_DataClient_Deployment_DocumentationThe product documentation provides details on how to deploy your runtime free license on target machines automatically, using your own installation program or how to embed the required license details into your application.

 

How is the developer license delivered?

OPC_Data_Client_Launcher_License_ManagerYou will receive a license file with your purchase, which you will then install on the development machine using the included License Manager Utility.  Using that same utility you can transfer your license to a different development computer. 

 

Do I have to pay annual fees to keep using my license?

OPC Data Client licenses are perpetual licenses. That means you own the license forever, as opposed to a subscription license where you have to pay an annual fee to keep using it. 

You do need to have an active Support & Maintenance Agreement in order to have access to phone and email support and product updates. 

Since you are developing an application that your user expects you to keep current with Windows OS updates and OPC specification updates, we highly recommend, but do not mandate, that you keep your Support & Maintenance Agreement active.

Do you offer hardware key/dongle licenses?

We do not offer hardware keys or dongles as a license delivery method.
