I've download the software and it appears that it's running just fine on Windows 10. I've used version IPS-v0.57a-Finale and there were no errors. The only thing I did was to run the software as Administrator to prevent additional errors.
You can download it through the following page: http://www.iw5edi.com/software/ip-sound
Right click the software, choose Run as Administrator (your username needs Administrator access) and then continue the installation procedure.
