Custom C#-OPUI - Are TestStand.Interop.* -references hardcoded?

[OnlyOne]

Hello,

i created an OPUI in Visula Studio 2012 C# which references from TestStand 2013 this:

NationalInstruments.TestStand.Interop.API

NationalInstruments.TestStand.Interop.UI

NationalInstruments.TestStand.Interop.UI.AxControls

NationalInstruments.TestStand.Interop.UI.Sopport

Everything is running fine under Windows 10 64bit.

Now i have the problem that my OPUI is not running with TestStand 2014 (64bit).

Do i simply have to replace the four references and recompile and everything is good?

The TestStand-process is starting (becaue i see the 7 days-evaluation window) but after i start the testplan i get:

Default Critical: 0 : System.Runtime.InteropServices.COMException (0xFFFFBC6B): Index out of range.
   bei NationalInstruments.TestStand.Interop.UI.ISequenceFileViewMgr.GetCommand(CommandKinds cmdKind, Int32 Index)
   bei NationalInstruments.TestStand.Interop.UI.Ax.AxSequenceFileViewMgr.GetCommand(CommandKinds cmdKind, Int32 index)

Is there any other way so that i can use any TestStand-version or do i always have to recompile?

Thanks

Hello OnlyOne,

i have a feeling you need to recompile the UI to a 64 Bit process. As far as I understand you build a UI for TS2013 and you would like to reuse it to call TS 2014 64 Bit. You are trying to call a 64 Bit process (TS Engine) from a 32 Bit process. This does not work and it could explain the "index out of range" error since you can not access all of the 64 Bit process' memory.

Disclaimer: I'm not too familiar with C# and Visual Studio.

Kind regards
