FMPP Error

[AD0TY]

When I try to run FMPP I get an error about a WSJT .dll file being the wrong type for my machine. Clicking close, closes the program, clicking ok cause the program to throw an error:

FMPP 1.13 -i1 -o1

Anybody know what I'm doing wrong? I've pretty much always used virtual audio cables with DSD, so I'm totally lost on setting up FMPP.

Never heard of that file and it doesn't exist on my PC, but FMPP works normally here, so what package is that file part of and how did you get an invocation of FMPP to try to load that DLL? Do you have all of the DLL files from the DLL package at dsdplus.com copied to your DSD+ folder?

 

[AD0TY]

WSJT is a piece of ham radio software that is completely unrelated, so I'm not sure why it is calling for a .dll from there, but I googled the file and found this: DSD+ 2.71 Error which solved my problem.

 

[slicerwizard]

I don't see any reference to that DLL in that thread. So what did you do that solved your problem?

 

[AD0TY]

The dll was libfftw something or other, which apparently is common with the other piece of software. Somehow DSD had found the file in the other softwares folder, but decided it wasn’t the right one, presumably because it was x86 and not x64. Downloading that dll package and dropping it in my DSD folder solved the issue.

 

[slicerwizard]

Ah, sounds like a 64 bit libfftw DLL was registered by the other software, and then you ran FMPP without the required 32 bit version present in the DSD+ folder. Windows tried to load the only version (the 64 bit version) it could find and crapped out with a machine type mismatch, and it wasn't a "WSJT DLL", but a "libfftw DLL in the WSJT folder" that Windows biatched about?
