Hello.

I will send you an evaluation license key by email. That will work with any version.

We do not officially support older versions. If you decide to use it, it is at your risk.
There is no special process to purchase older versions: They are available for download from kb.opclabs.com/Versions , and any license key works with older versions too. So you would basically purchase the current version, and that entitles you to older versions as well.

Best regards

Quick OPC 5.35 Trail and Licensing Options was created by shawn.hesch
Hello,

I am working on an application running .net framework 4.5 on Windows Server 2012. The application needs to have it's OPC service (currently ClientAce) replaced with another solution.

QuickOPC 5.35 appears to be a suitable solution, but I would like to be able to trial the software to ensure it meets all of our needs before purchasing a full license.
I have run the QuickOPC 5.35 installer, but when attempting to run the demo application, a trail error occurs "Not allowed to run by the license. You might be using a trial license, and the version of the software you are using is obsolete. Obtain a recent version to resolve this problem."

I have seen elsewhere on the forums that evaluation licenses have been given for trialing older versions of the software, would that be an option to resolve this issue?

Secondly, I would like to confirm that a full license can be purchased for QuickOPC 5.35, and that it isn't obsolete.

Regards,
Shawn
