Do you have the LabVIEW Runtime Engine running on the client computer?  I believe this used to be required, although I don't know if it still is.  The error message does seem to indicate that there is a server-side issue, but who knows?

Hi EdDeWitt: 


Thanks for your reply.


May I ask one question, since I am very new in using LabView, so many things I don't know.


Vision Run-Time Engines and  LabVIEW Runtime Engine, this two type of engine is same? 


Thank You.

I don't know the answer to that one.  I am sure someone more knowledgeable will reply, and hopefully lead you to a solution.

Just now, I install LV run time engine already. Also same problem occur. 


So, I think not run time engine problem.


Maybe is other problem.


And then, EdDeWitt, you know what is meaning for this sentence.

" To display VI front panels on the Web, the VIs must be in memory on your computer " 


Thank You for helping.

Have you had a look at the following KB article:

Requested VI is Not Loaded into Memory on the Server Computer


A VI is considered to be in memory whenever the program is open on the server machine. The VI does not have to be running. 


If the KB article linked above doesn't help, I would want to know what LabVIEW system are you running on your system and how many connections have you setup to the server. The LabVIEW Base and Full Development Systems include a remote front panel license that allows one client connection. The LabVIEW Professional Development System includes a remote front panel license that allows five client connections. Just wondering if that might be causing problems.
