Error when calling DLL's functions in another computer.

When I execute the installation program in another computer it happens a problem in the call of the functions of a DLL that I created. The calls are made through the function CallInstDLL. The functions of DLL don't execute in the other computer! Which the reasons that can make that to happen?

A bit of the source code (entry point to dll and such) would help! Did you use ExDll examples to produce the plugin?

-Stu

Yes, in the same model of the example for Delphi...
What I might have forgotten?

You might have some hard coded paths or you might have forgotten to extract the DLL, but it's impossible to tell without any details.
