QuickOPC - Licensing - Upgrade or new license to purchase

11 Jan 2016 17:13 #3742 by support
Dear Sir,
thank you for your interest in our products.

The licenses currently sold are for QuickOPC version 5.22 to 5.3x (as stated on the purchase page). They cannot technically work with version 5.12, because the format of the license has changed in between.

Without going to relatively big hassles, we do not have ability to generate license for such old versions any more. I strongly advise you to update your code for the newest version. I will be happy to assist you in resolving the differences - they are *not* big, it should be a straightforward task to do. Just because it gives many errors during compilation does not mean it is difficult to fix...

Best regards
Zbynek Zahradnik

Dear Support,

We recently purchased license for OPLABs QuickOPC (standard single developer + runtime free license).

We developed a plugin for importing live data off OPC DA server using OPCLABs product version 5.1.2 as a proof of concept (obviously few years ago).

We now have a customer wanting to use the plugin so we purchased license for 5.3.x. We installed License Manager manually and uploaded license for production on customers computer. The customer still only gets data for 30 minutes and we still get error that says we're on trial version.

So first question: Why does license fail?

We installed QuicOPC on development PC and tried to build app with latest version 5.3.x, and got a bunch of errors - so a lot of changes between versions. We would rather not change our code.

Second question: Is there a way to get customer up and running on version 5.1.x?

If you have a license for version 5.2x, you need an upgrade in order to use version 5.3x, *unless* you are covered by an active maintenance period (in which case you are licensed to all versions released during the maintenance period).

All version upgrades are currently priced at 50% of the new license price. They can be purchased online as well, but with a discount coupon that you get after identifying your existing license to us. We need e.g. a serial number, invoice number, or your official company name and date of purchase; use the Contact Form on this site, or email to sales09(at), to provide that info.

Best regards
