Hello, I have created a distribution kit for my program.The problem is that the when the program is installed onto another computer, it fails to communicate with field point (Using FP-AO-200 and FP-AO-1000). Help is greatly appreciated, Thanks faen9901

Question

Hi Everyone,
I have a program that sends information(analog output) to lab windows cvi in the form of a text file or user input.
The program runs on the computers that I have the field point explorer and lab windows cvi installed on. In order to run the program without always installing labwindows/cvi and field point; I wanted to create an executable file that could be load on another computer.
I used the create distribution kit part of labwindows/cvi to do this.After creating the distribution kit, I then installed it
to another computer.
My user interface appears on the screen, when the user clicks on the exe. file, but no data is sent to the field point module. I know that the data is being read from the user and textfile because in it appears in the uir.
The following are some details about the problem:
1. On another computer without labwindows/cvi and field point explorer not installed - no data is sent to field point module
I know this because a current is being read on the current meter connected to field point module.
My questions are the following:
1. What are the possible reasons for the data not being sent to the field point module?
2. Do I still need to create an iak. (Installing Field point Explorer) file stored on any new computer that I install my created distribution kit file too?
Thankyou very much for any help that you can provide. I greatly appreciate it.

1) If you do not install FieldPoint Explorer, the FieldPoint Server is not installed so there is nothing on the target computer that knows how to talk to the FieldPoint system.
2) Yes, you need an IAK file on the target computer. Assuming the settings (i.e. com port#) are identical you can simply include the iak file as part of the distribution.
3) You also need to include as part of your installer the file "fplwmgr.dll". If this file is not installed, your program will not be able to access the FieldPoint Server. Alternatively, this file is installed automatically if FieldPoint Explorer detects LabWindows/CVI or Measurement Studio Development versions on the target computer or if you choose to do a custom FieldPoint Explorer installation and
choose to provide LabWindows/CVI support.
