Issue Details

I have created a sequence in TestStand 64-bit and I am trying to connect it to LabVIEW 32-bit code modules. With the adapter set to 32-bit LabVIEW Run-Time Engine, I cannot run my sequence and I can't change the versions of the code modules.


Although it is always best to plan ahead and ensure that you are using the same bitness of code module and test management software, this might not always be possible.

It is possible with NI TestStand to run sequences saved as a 64-bit sequences with TestStand 32-bit.
Therefore, if your application allows, you should change to TestStand 32-bit to run your 64-bit saved TestStand sequences. This will enable you to run any code modules on the 32-bit Run-Time Engine adapter setting with TestStand 32-bit.

If this is unsuccessful, please contact Technical Support.
