Unified Automation Forum

Hi,

I'm working in C#, I have created 2 OPC client :
- 1 using the wrapper OpcNetApi.dll
- 1 using the wrapper interop.OPCAutomation.dll

they both working fine when my application is targeting 32bits (on windows 7 64bits) but none of them is working when targeting 64bits. Is there a way to make one of them work with 64bits?
is there another wrapper that can do it?

thank you for your responses

The files you refer are redistributables of the OPC Foundation. Not all version of such files properly support 64bit, you must look for the latest versions of the core redistributable packages.

Please contact the OPC Foundation, to get the latest version and the changelogs to identify what you need.

Best Regards
