An error occurred loading VI'AI Group Config.vi,.

[briandemurihaeberle]

I am trying to move a program from windows 98 to my laptop which runs XP and I keep getting the following two error messages when I try to run the program:

1. An error occurred loading VI'AI Group Config.vi,. LabVIEW load error code 21: An external subroutine required for execution could not be found

2. Error - 10243 occurred at DIO Port Config.

Does anybody have suggestions as how to fix these errors?

Is this program an executable ? Have you installed the DAQ drivers on the computer running WXP ? If not an executable, have you also installed the DAQ LV support ?

This program is an executable and I have installed the DAQ drivers I downloaded from the NI website.

Hello,

It it very possible that you have developed your application (.exe) with one version of the NI-DAQ driver on the 98 machine and have loaded a different version of NI-DAQ on to the XP machine.  This would explain both error 21 and 10243.  There are only a couple of versions of the NI-DAQ driver that support both 98 and XP.  Thus, it is very likely that you could have developed on the 98 machine with a version of NI-DAQ that does not support XP.  Please check that you are developing on 98 with either of these versions of NI-DAQ 6.9.0, 6.9.3 with patch 6.9.3f5, 7.0, or 7.1.  I would recommend using 7.1, since it is the most recent of the Traditional NI-DAQ drivers that support both OS.  If you find that your .exe was developed with a version older than 6.9.0 you might need to upgrade the driver on the developement machine.

Please also make sure that you are using the same version of LabVIEW and DAQ driver on both the developement and target machine.
