@wesner0019, if you have winzip or 7zip or winrar, you should be able to right-click on the file and open it as an archive. If so, open the .tar file which is also an archive. Once open, open the directory you will see (dfu-util-0.8-binaries) and you will see the win32-mingw32 directory. The contents of that directory need to replace the ones in the directory on your PC.
