Thank you for the response. That's a good question. I'm not 100% sure. There is only a .dll file, no .xs file. I think that the .dll is created when I install the program because there is no ifeffit.dll (or .xs) on the github site, though I suppose it could have brought it in from elsewhere.

I have a working copy of the software on a WinXP and there is also only a .dll. That .dll of course does not work on the Win7 computer, but it does give a different error than the correct .dll.
