Error -1073807202

[Pablop]

My LV program uses serial port communication to run a micropressor ASIC programming station. Works fine on several XP installations, but on 2 separate W2K computer stations (older PC's) I get this error:

(from the "Explain Error" help file, see jpeg for more info on actual event)
***************************************
Error -1073807202 occurred at an unidentified location

Possible reason(s):

LabVIEW:  (Hex 0xBFFF009E) VISA or a code library required by VISA could not be located or loaded.
=========================
VISA:  (Hex 0xBFFF009E) A code library required by VISA could not be located or loaded.
***************************************

The VI that generates this error is essentially the NI example for serial port communications with the basic paramters changed to suit my application. See attached jpeg. Do I have to do something specail when I build the exe file to include visa files for W2K installations?

Any suggestions?

Yes, you do have to include the NI-VISA library.  This error message occurs when the VISA library is not installed.  Look at this recent thread for some help  http://forums.ni.com/ni/board/message?board.id=170&message.id=271303&query.id=436446#M271303.

If you search the forums with your error number, you usually find that someone else has already had the same problem.  Make sure you search the number as 1073807202 without the negative sign.  If you search it with, you'll usually get no results because the minus sign has a special meaning in the search dialog box.
