hp7550,
You are right. It doesn't work. I reported it. You can also grab it from our FTP site at:
ftp://ftp.ni.com/support/labwindows/cvi/runtime/7.0/win32/
If for some reason that doesn't work, like you hinted in your third question, you can create a distribution kit for your operator interface (assuming it was written in CVI), which will get the CVI run-time engine on your target machine. By the way, the operator interface should be called testexec.exe; so the operator interface and testexec.exe are the same thing.
Yes, if your TestStand sequence calls CVI code (DLLs, EXE), you will need to install the CVI run-time engine on every machine that your TestStand sequence runs on.
To answer your third question, as I already mentioned,
you can distribute your operator interface using a CVI distribution kit. You can also deploy it with the TestStand deployment utility. Just include the testexe.exe file in your TestStand workspace.
