Hi from Germany,
I have to update some OPC samples, written in C# and Visual Basic for .Net.
These older .Net samples, using OPC DA, are compiled for x86 and they are running with the following DLL:
opcrcw.da.dll (Version 3.0.101.0, Description: OPC Data Access 3.00 .NET Wrapper)
The opcrcw.da.dll is a 32 bit DLL.
The task is to compile the samples for x64 (or AnyCPU).
Question:
Is the opcrcw.da.dll available for 64 bit?
If yes, where?
Thanks a lot,
Carsten

The latest RCW is architecture independent:
2.01.108 | Release | OPC NET RCW (NuGet/ZIP) |

You need to upgrade.
