debug into code "connection_windows.go", line of 473, "err = items.Add(tags...)", here items' addItemObject is with ole.IUnknown for "unreadable : could not resolve interface type", what's the problem?

Please compile it for GOARCH=386 (see here)

thanks for your help, but it seems still not works.
I just try both of the DLL(OPCDAAuto.dll/gbda_aut.dll) and compile it for amd64/386, all below:
1、download and unzip the "graybox_opc_automation_wrapper", get x86/gbda_aut.dll and copy to C:\Windows\SysWOW64, install with cmd regsvr32 gbda_aut.dll (and try over the x64/gbda_aut.dll to C:\Windows\System32, or SysWOW64), go env set s GOARCH=386
2、register Gray Simulator with cmd "gb_opcsim -service"
3、compile main.go with build.bat:

CGO_ENABLED=0
GOOS=windows
GOARCH=386
go mod download
go mod tidy
go build -o ./main.exe .

run it still occured error above.
the MatrikonOPC Server Simulation and MatrikonOPC Explorer can both works well and show the item value.

However, i just try it all over again and succeed. Thanks !
