Application Builder 7.1: problem when running an EXE

Question

Hello,
I have developped a VI on a computer with LabView 7.1. The VI uses an USB 6008 (with DAQmx base 1.4 drivers.) to measure signals. It perfectly works. Now I've spent a lot of trying to put the system on a computer that doesn't have LabView installed.
-I first installed the USB 6008 drivers on the computer
-Then I made an installer with the application builder (including the run-time engine)
-Once the application is installed on the new environnement, I just keep on having error messages when running it.
  -first it doesnt find all the DLL, you have to copy them from the PC with LabView in C:\windows\system32\.   Done.
  -then I get this big dialog box with a listing of sub-Vi missing, such as: Sub-VI Create Task.vi missing in VI Instance 1  6ProgName.v1
   I've looked into the LLB file created with the builder: all these sub-VI are here!! Why won't it work?
What can I do to solve this?? Thanks for your help.

Hi  batsenn,
for the missing dll: what are those dll's? you may need to install additional run-time packages, or check some more component in the Advanced Installer Settings form, depending on your application.
Now for the main problem: are you calling vi's dynamically from an external LLB? in many cases when a file is not found from the built application, it's a path problem. In fact, if a vi path is e.g. c:\mysourcedir\myvi.vi, when the EXE is built the path will be something like c:\myexedir\myexe.exe\myvi.vy. You see that there is an additional Strip Path you need to do if you are getting the current path from a vi path.
What I said can be relevant or not depending on the vi calling techinique you are using. A suggestion is to execute the built EXE on the development computer (where all components are present) to check if the problem is still there.
Hope this helps.
