Error -17600 when switching from LabVIEW Development System to LabVIEW Run-Time Engine in Adapter Configuration

Question

I receive an error message (code -17600) while loading my test sequence after switching from LabVIEW Development System (2009 f3) to LabVIEW Run-TIme Engine using the Adapter Configuration.
ErrorCode: -17600,
Failed to load a required step's associated module.
LabVIEW Run-Time Engine version 9.0.1f3.
When I switch back to the LV development system, everything is OK, and the sequence loads and runs perfectly.
My TestStand Engine Version is 2012 f1 (5.0.0.262).
I'd appreciate any help on this issue.

Hi Roman,
There are a couple of things you can try:
1) Determine if the LabVIEW RunTime Engine is corrupted in some way. Create a new simple VI with no sub-VIs, using the same LabVIEW Development system you used for mass-compiling the VIs. Create a TestStand step that calls this VI and ensure it runs correctly. Now switch your LabVIEW adapter to use the RuntimeEngine and choose the "Auto detect using VI version" option.
Check if the simple VI is loadable and runs without errors in TestStand.
If the step generates the same error, you should try a re-install of the LabVIEW development system.
If not, its most likely that there is some VI you are using that is not loadable in the LabVIEW Runtime Engine because:
1) Some sub-VI is still not saved in the right version or bitness. Open the VI heirarchy of the top-level VI that you are calling from TestStand and examine the paths of all the sub-VIs to check if they were in the folder you masscompiled and re-save any that are outside this directory.
Also, when you try to close the top level VI, do you get a prompt to save any unsaved files? If so, they could be the sub-VIs that are not saved in the right version. Save all of them.
Check if you are loading any VIs programatically and if these are compiled and saved in the right version as well.
2) There is some feature you are using in your LabVIEW code that is not supported in the LabVIEW RunTime Engine. To check this, add your top-level VI to a LabVIEW project and create a new build specification and create a new executable from this VI.
    Right-click "Build Specifications" and choose "New->Application(EXE)".
    In the Application Properties window, select Source Files and choose the top level VI as the start-up VI.
    Save the properties.
    Right-click on the newly created build specification and choose Build.
Run this executable (it will be run using the LabVIEW RunTime) and check if the VI has a broken arrow indicating that it cannot be loaded and run in the LabVIEW Runtime Engine.
You might need to examine your code and find the feature which is not supported in the LabVIEW RunTime and find an alternative.
Another thing i forgot to mention the last time around is if you are using 64-bit LabVIEW with 32-bit TestStand, then executing code using LabVIEW RTE from TestStand will not work since the 64-bit LabVIEW RTE dll cannot be loaded by the 32-bit TestStand process.
If none of the above steps resolve the issue, consider sharing your LabVIEW code so i can take a look.
