Here are some steps:
1. Open TestStand.
2. Make sure the LabView Adapter is displayed in the pull-down menu near the middle of the icon window (top). When you pull it down, it gives selections such as C++/dll, Active-X, Sequence, etc. Leave it at Labview.
Since you already have an existing vi, I will describe the steps accordingly.
3. Place the cursor in the blank new sequence file window.
4. Right-click and select "Insert Step"
5. Select (LV) "Action". You can choose one of the tests, but since it is already created, the vi may or may not have the necessary terminals to permit a test. You can experiment later on this.
6. Write in the box (at left of window) what this step does. In other words, briefly describe what your vi does.
7. Click on that new line to select it. It will turn blue.
8. Right click it and select "Specify Module".
9. Browse and select the vi that was already created. I will not go into details at this point since I do not know which version of TestStand that you have. I find the latest version 3.0 to be the best. After selecting the vi, the name shows up in "VI Pathname". Click "OK" to close that window.
10. The vi should now appear in the new sequence file to the right of the brief description that you previously entered.
11. You may have to initialize certain values before running the sequence. You may also need to "cleanup" or close communications, etc. Details of this can be found in the TestStand discussion forum.
12. Assuming everything is ready, simply press "F5" on the keyboard or click the run icon or under "Execute => Test UUT" to start the sequence and run your vi.
That's it!

PS: LabWindows CVI is actually an environment to develop C-style software that can be called by either TestStand or Labview. I usually use it to prepare device drivers. I never tried calling vi's using CVI, but I think you can..
To call a CVI within TestStand, simply follow the steps above, but change the Adapter to "C/C++ DLL" in TestStand.
