QuickOPC .NET : blocking issue on windows 7 x64

Unfortunately, this suffers from the "works on my machine" issue. I have tested (the recent build of QuickOPC 5.34) on a fresh Windows 7/64-bits machine, and EasyOpcNetDemo.exe runs fine there (and, I have verified that it is running in a 64-bit process).

The error you have mentioned usually has to do with missing prerequisites; namely, Visual C++ Redistributables. The setup program is, of course, supposed to install them for you. When you go to "Programs and Features" in the "Control Panel", do you see both of these?:

Microsoft Visual C++ 2013 Redistributable (x64) - 12.0.21005
Microsoft Visual C++ 2013 Redistributable (x86) - 12.0.21005

(please also compare the precise build numbers).

And, when have you downloaded the QuickOPC 5.34 setup? (OK if in recent 3 months)

Best regards

Hello.

Was QuickOPC installed on the target computer using its own setup program, or have you followed the steps described in the "Application Deployment" section of the "Concepts" document, in case the installation program has not been used?

Thank you

QuickOPC .NET : blocking issue on windows 7 x64 was created by s-petit@hotmail.fr
Hi,

I tried EasyOPC 5.34 on windows 7 64 bits an had an issue : unexpected exception occurs. I tried with demo application "EasyOpcNetDemo.exe" and had the same issue. (i just click on the "browser servers" button and after a few seconds, exception occurs)

If i start the demo project with VS in debug, i have a SEHException in App_Web_OpcLabs.EasyOpcClassicRaw.amd64.dll.

I tried to set project plateform to x86 instead of AnyCPU and the same test works fine.
Do you have any idea of what may cause this issue ?

Thanks.
