Geo SCADA Expert 2021 Running on Windows Server OS - ViewX Crash App Error 1026

[Aundrea_LaTech]

I have a few separate Geo SCADA Sites that are experiencing an issue where ViewX crashes as soon as you launch it. It shows the splash screen for a brief moment then crashes. In Windows Server Event Viewer the crash shows up as Application Error 1026.

I am running the latest version of Geo SCADA 2021 v84.8335.2. I am seeing this issue on three separate systems: Windows Server 2016, Windows Server 2012, and Windows Server 2019. 

I assume that there was a Windows Update that caused this issue. I have tried a number of ideas I found online to resolve the .NET error 1026. Nothing has worked.

Has anyone else seen this issue and resolved it?

You really need to raise this issue with customer support and supply the ViewX log files and the mini-dump file. A generic .NET error code doesn't tell us anything useful by itself.

However, as a guess this might be caused by installing both Geo SCADA and Virtual ViewX on the same server and only upgrading Geo SCADA so the two versions no longer match.

I thought the community might be able to respond faster than tech support with some feedback. We have already reached out to tech support and we are waiting for response.

One customer with this issue is running 2015 R2 and there is no Virtual ViewX involved. We will wait to hear back from tech support.

Sorry Aundrea, the answer here's not easily discerned! What Windows Updates were recently installed (the KB numbers)? Is there a dump file (.mdmp) for the crash (if so send to support)? It could be a .Net issue - Microsoft offer a repair tool: https://www.microsoft.com/en-gb/download/details.aspx?id=30135

Steve,

I am happy to say that I updated to Geo SCADA 2022 today and it resolved my issue!! I had tried the .NET repair tool many times with no luck. If any of my customers experience this I will recommend to upgrade to the Geo SCADA 2022. Thank you for your reply on this issue. Happy New Year!!

Just to chime in and add my experience -- I've had this happen a few times and most every time it's resolved by reinstalling or repairing the Geo SCADA server install.  I think what Andrew described is exactly the issue I've run into where it's something in VVX or GS not registering properly. 

In your case where it's all 2015R2 with no VVX, it's likely a .NET or C++ redistributable issue.  In older versions I've had instances where I had to go and remove some of the "newer" C++ components and install the ones bundled with CS just to get it to work. 

All that said -- you did the right thing going to 2022 as 2015 is way out of support anyway.
