CallDLLFx Problems

I'm new to InstallShield, so I may be missing something obvious, but others who've had experience can't solve my problem either:

I have tried to use CallDLLFx to call a DLL function which is visible (I've used the Dependency Walker in VC++), but I keep getting -1 return codes.
I have tried altering the destination function, with Exclaims and MessageBoxes, but it isn't even being called.  I've also tried moving the DLL to C:\, but with no luck.  The problem is happening in a number of places with the same DLL, which has worked before perfectly.

Any ideas???  I'm desperate!

Thanks in advance

Make sure that all of the required dll's are available on the machine as well.  For your dll to work, you may also required a couple others.

  Why are you using CallDLLFx and not just prototyping the function?
