Issue Details

I have a LabVIEW VI written with LabVIEW 64-bit and I want to run this in TestStand 32-bit using the Runtime adapter. Is this possible?


It is not possible to run a 64-bit LabVIEW VI in the LabVIEW Runtime Engine in TestStand 32-bit.
However, it is possible to run this with the LabVIEW Development System by configuring the adapter under the Adapter Configuration.

Additional Information

This works in the Development Environment because TestStand can call the LabVIEW.exe as a separate process.. However, the LabVIEW Run-Time Engine is a DLL and cannot be called separately; this must be in-process in the TestStand thread.
