Hello.

It looks that I was able to reproduce the issue. No further action is needed from you at this point. It will take some time to investigate; I will post here then.

Best regards

Thank you for this.

My plan is now to install a new machine (VM in Azure) with Windows 10 version 2004, the OPC server, the appropriate QuickOPC version, and attempt to reproduce the issue.

If I fail to reproduce it with test programs of my own, I will also ask you for a copy of your software.

I will post here when I have an update.
Best regards

Hi,
See the customer's answer below.

We installed this same UCME software in Server OS , Windows 10 with Version 1803 but it’s working fine for OPC Browser.

The OPC server is the part of Wonderware Intouch 2017 update 3 SP1 P01.

Thank you.

Michael

Hi,

Thank you for your answer. I have asked the customer to provide us the exact Archestra version number. We shall download this version and test it in our office on the same Windows 10 version 2004.

Regards,

Michael

Thank you. I see, the error is indeed very similar, now I understand why: It is accessing the same component (OPCEnum) - just no for server browsing, but for conversion of ProgID to CLSID. This means that it might be possible to get at least the item browsing (browsing "into" the server) by using its CLSID in the curly brackets ( {...} ) instead of ProgID. But that's not resolving the real problem, and also won't help with server browsing.

I have hard time with error. It appears in a simple function that has no obvious bug, and has been working for almost 20 years without problem. I suspect WIndows 10 version 2004, because I have now some reports of weird things happening on *just* that version (reverting the Windows 10 version resolves the issues). But, I have Windows 10 version 2004 on a test computer as well, and could not reproduce the problem. So I would rather suspect something else peculiar about those machines.

I really need a reproducible scenario (i.e. probably figure out a combination of the software that triggers this); without it, it would be difficult to troubleshoot the problem. About my only choice would be to try to re-program the particular function (as there are different ways to do the required operations, so even if there is no bug but one way does not work, doing it differently may help). But that would be cumbersome and is is basically like shooting into the dark.
