I installed Proxomitron in "C:\Program Files (x86)\Proxomitron", the replacement default.cfg has been copied to that folder. And I downloaded and copied the zlib.dll, libeay32.dll, ssleay32.dll, and msvcrt70.dll into the Proxomitron folder as per your other thread.
Yet the "HTTP 1.1 404 Not Found" errors persist in PVD.
I've tried disabling both my antivirus and firewall (Avast and Comodo, respectively) to no effect.
I just don't know what's going on here...
