Call VIs in LabVIEW 32-bit and 64-bit simultaneously

Hello,

 

we forced to call some VIs in LabVIEW 32-bit due to .NET DLLs inside not being capable of 64-bit.

However we do not want to run all LabVIEW VIs in the application in 32-bit just due to those few.

 

The idea is to run the DLL wrapping VIs in the Runtime Engine (32-bit) and set the adapter in TestStand to 64-bit.

 

Everything works as expected when the adapter is set to development system 32-bit.

As soon as I change the adapter to LabVIEW development system 64-bit, many VIs from the runtime engine throw errors for unfound SubVIs / Controls, e.g.
Sequence Context.ctl. Error Cluster from Code.vi etc.

 

Is our attempt possible at all and has anybody encountered these issues before?

 

Thanks.

 

Stefan
