can build a DLL, but cannot run it on another pc

I have built a very simple DLL using Intel fortran.  I can successfully call a routine in it from an Excel visual basic macro on my own computer, but not on another computer.  I get a message about "file not found" and "error 53".

I think the right compiler options are what I'm looking for.  Can anyone tell me what I need to do?

So far I'm doing everything with 32 bit options, and Excel is a 32 bit version.  Once I get this working, I want to get it working for 64 bit Excel.

Thanks,

Brian
