I have synergy installed and working but am experiencing the choppy mousing issue. Is the interbox software still being supported and/or updated?

I downloaded these last shared files, tried to install the 86.zip and got the following error: the application has failed to start because its side-by-side configuration is incorrect. Please see the application event log for more details. The 64.zip I got this error: not a valid Win32 application.

My machine is using Windows Vista, 32bit. I attempted these installations as Admin.
