Hello.
For QuickOPC 2020.2, when targeting .NET Framework, the supported operating systems are:
So yes, for "Client" operating systems, it is only Windows 10. QuickOPC 2019.1 which I think you have been using so far also included "Windows 7 (x86 or x64) with SP1". We usually do not support operating systems which their vendor (Microsoft) no longer generally supports.
If you are using the same license key then the registry keys stay the same.
I am not aware of other changes that would be needed.
Best regards

Ok, great. I downloaded and checking out now. It does look like now the new assemblies will ONLY work on Windows 10 correct? That is fine, just wanted to make sure.
So as for deployment, a couple questions. In the past I have included the necessary assemblies (OpcLabs.BaseLib.dll, OpcLabs.EasyOpcClassic.dll, OpcLabs.EasyOpcUA.dll) in my custom installer package and then installed registry entries for the license info to the user PC. For this upgrade, I plan to just replace those 3 assemblies with new 2020.2 assemblies. Do I need to update the Registry info since the current license we have covers this version? Anything else required?
Thanks again.

I have checked your license and you have free upgrades for all versions released until October 2024, so you are all set in this respect. You can download it from here: www.opclabs.com/products/quickopc/downloads . Make sure you reference the newly installed assemblies and rebuild.
When we release a new version, it is always tested, and the test includes the latest supported Windows version (which is usually the latest currently available). So, it works well at that point in time. But, it has happened several times in the past, that Microsoft releases a new Windows update (version) that breaks something, and that "something" was frequently related to the BoxedApp SDK. So the library vendors then update their BoxedApp SDK, and at next opportunity we update QuickOPC with that newer SDK, and it fixes the problem. Ideally we would like to get rid of this dependence, but it serves a good purpose in our software - when it works. And when it does not, then comes the need of disabling it.
For upgrade from 2019.1 I do not expect any code changes, or very minor ones. If you run into any issues, we are here to help. The list of changes for each version is here: kb.opclabs.com/Versions (clicking in the column "Key Changes - What's New" leads to detailed pages).

Ok, thank you for clarifying. Could I get a version to try to make sure it resolves this issue before we purchase? Or is it a free update?
Also, do you anticipate any other changes to the code (as shown below) to update to this latest release? Would this update eliminate the need for the boxed disabling parameters in the exe.config file?

Hello,
the information available to me, at the current date, is that nobody that is using QuickOPC 2020.2 Build 451.1+ is having these problems, on any Windows 10 version. But one must take into account that it is quite a new build (2 weeks old now), so the number of active users is probably very low. I cannot tell with higher certainty, because of this. We should also be releasing version 2020.3 in December, which will be the same in this respect (BoxedApp SDK version used).
Best regards

Ok, so an update from my side ... It looks like other team members have been updating to Windows 10 and at this point downgrading to older versions of Win 10 (pre 2004) isnt an option for us. What's weird is that I do have one machine with Windows 10 Version 1903 (Build 18362.356) circa 2019 that isn't seeing this problem.
But honestly, with the nature of how we deploy teams to different test sites, controlling a specific version of WIndows 10 will be tough in some cases. If you are saying that just updating the API to 2020.3 is the cure-all in all cases, looks like I will need to do that. Is that correct? Is the latest API a surefire fix for all versions of WIndows 10?

No, I mean older. It is Windows 10 version 2004 and later that broke these things.

I did check the app config file and does look like the disabling the prereq boxing has already been disabled as described in the link. I think that may have already been done for a past issue.
So at this point, it looks like we should update Win 10 to latest or update Quick OPC. You say use Windows 10 "older" than version 2004 but do you actually mean a later version? such as more current? We have a 2019 version we could use. I would rather start with a Windows update if that will correct the problem, and only update the API if necessary.

Hello.
You need to either
1) use Windows 10 older than version 2004 (what you have is version 2004), or
2) upgrade to QuickOPC 2020.2 build 451.1 or later, or
3) try to work around using the technique described here: kb.opclabs.com/How_to_disable_prerequisites_boxing
Best regards
