As of September 2009, PTC stopped using Aphelion and are now using WindchillDS (Windchill Directory Service), which uses the Java OpenDS protocol. There was some overlap and for a few maintenance releases of Windchill it could use either. But now they only support the use of WindchillDS.
This software has worked great. I own a computer repair store and have installed it on almost every computer that has came in that was running slow. I love free Glary Utilities with unlimited functions.
Glary Utilities 6.3.0.6
YET YOU SAY I NEED TO UPDATE IT.
