Application Builder - Call Library Function

[physicsandfrench]

I use the call library function in several places in my project to call functions from a C++ library. The program works as a labview vi, but when I build the application it never works at all and the dlls never get called which is part of the initialization stage. The only errors generated are a series of time outs. I'm open to any suggestions.

I don't know what you are actually doing in the function calls of the DLL.
But you say you are getting timeouts. Who is the originator of the timeouts? Your DLL code or your LabVIEW code? If it is the DLL code -> your DLL functions were called.
If not, verify if your DLL functions are called by LabVIEW (even the application), please insert a MessageBox() in the DLL function call that executes first.
I expect that you executed the application on the same computer as you are developing in LabVIEW, is it?  If not, you might be in "DLL hell".

If all of this does not help: Can you give any further details what you DLL code is doing?
